GTS 4 Mini Smart Watch for Women Men, Alexa Built-in, GPS, Fitness Tracker with 120+ Sport Modes, 15-Day Battery Life, Heart Rate Blood Oxygen Monitor, Android Phone iPhone Compatible-Black

Very good product. I have been using it for years now with no problem. It’s battery is amazing.and it charges so fast. And it lasts easily for over a week, at least.

I had just a knock off watch that counted steps and heart rate and after 7 years it bit the dust. I looked into getting a smart watch. Boy oh boy are there a lot of them and the range of prices and I was a little overwhelmed. I somehow got linked up with a survey on what I was looking for in a smart watch and it picked the Amazfit GTS mini-4. Also, for the price of $120.00 Most of the smart watches were well above the $250 price range and offered so many features. After all said and done I did my research and compared it to all the other named brand watches, and this fit into what I was looking for. It has all the same features as the name brands and probably half the cost. It came with a watch, wrist band and even its own charger. - (unlike some of them you had to buy the charger separate. Very simple instructions to set up and put the app on your phone. (yes, it is a third-party app but there is no cost) After having /wearing the watch for almost 2 weeks. I will say the battery charge holds very well. It was down to 30% after wearing it nonstop for 13 days. There are lots of different setting you can do with the watch. You are able to make in app purchases to add more items to the watch , or change the face of the watch. I especially like some of the features as the sleeping pattern, pinging of the watch or phone to locate. There are plenty of other features that I have not even tapped into yet. My only dislike is the band itself. I feel as it could be bigger/longer. But I wouldn't give it negative rating for that it is just a personal preference. All in all if you are looking for a smart watch and don't want to pay all the extra money for a name brand watch this is the one for you.

Most of the features work as advertised, I slept with the watch on my wrist and the sleep time was correct. The steps matched the steps on my apple fitness app, and the heart rate seems correct. The Zepp app was easy to use in the setup process, the app offers watch faces, some free, others you have to buy, but their very cheap. I also like the fitness notificiation that alerts you take a walk if your sitting for a long time. The battery is good, after 7 hours of sleep the battery was at 88%. the only con is that some of the features on the app require a watch upgrade and the weight tracker feature isn't available for this version. Overall, I'm happy with this tracker

I've been wearing it for 11days now and so far it has exceeded my expectations. Battery Life: I fully charged it the first day and now it's 34% (11 days later). I have the watch display set to turn on when I raise my arm only. I have the watch tracking only about half the health data it could be tracking and I have it reassess my heart rate every 30min. The only alerts I allow are calls, texts, calendar, and Amazon notifications. I wear it all night when I sleep. So I'd say my usage is moderate. I would imagine with the Always On Display and having it track every health option it would consume the battery much faster. My charge time was about 2 hours. Battery Life (UPDATE): When I don't track my sleep with it and by putting the watch on Battery Saver mode while not using it (like at night) I charged it to 80% and then 20days later its now 38%. App Compatibility: It works with all the essential apps, it even works with Whatsapp. Health Tracking: So far everything seems accurate except for one problem. I work the night shift and the watch doesn't seem to understand how to track my sleep when I sleep during the day. It says my sleep is 100% light sleep only when I know for a fact that's not true since I am a very deep sleeper when I dream. When it tracks my sleep at night, it records very well. The Button: That button on the side is just a button, it doesn't scroll. You can program it to do certain shortcuts when you press it or hold it. The Display: It's plenty bright and it has auto dimming which is cool. As you can see in the photo, you can select a custom photo as your background (I chose a Batman them). The resolution is nice on the eyes and the screen is very responsive. It's not a flagship screen swiping experience but it's pretty dang close and it's hardly anything to complain about since the price for a watch of this caliber is unmatched. Water Resistance: You can definitely swim with this, no problems there at all. It will still display the time under water when I turn my wrist over, but the swiping feature doesn't work until you get it out of the water. Comfort: I always forget I'm wearing it. It's so light and the wrist strap never slips or irritates me. I wear it when I sleep and it never bothers me. The only time I take it off is when I shower or workout (I could leave it on for those things but I choose not to). This watch is great. I only say that's it's "almost" the best is because it doesn't know how to track sleep during the day. Other than that, this watch does everything you need a smartwatch to do, minus being able to respond to calls or messages through the watch. I don't need or want that feature anyways, that's what I got a phone for. I use a Samsung Galaxy S22 Ultra and so far I don't have any compatibility issues. Took me a couple days of playing around with the watch's app to fine tune it so the watch runs the way I want it to, but the app was pretty straight forward. Love this watch, would recommend to anyone.

I've had the following watches: Moto 360, ZenWatch 2, Galaxy Watch (1 & 3). Most of those met an untimely end due to ONE issue, the firmware would get updated and the device would become unbearably slow. Google Watch OS or Tizen OS, didn't matter. The Moto, however, had display issues that Moto wanted me to pay for fixing (under warranty). These are a breath of fresh air. No fancy gimmicks or useless gizmos. They did a great job including features that are useful but not wasteful. Most importantly, the OS (i think it's RTOS) means it's never slow. The battery life is great. I went on a week long trip to my sister's place and didn't need to bring a charger. Used AOD 50% of the time (timed to turn off after 8pm, back on at 8am). If you want a smart watch that you can receive notifications with, but that doesn't require you to watch the battery percentage all day, this is fantastic at it. Couple of caveats (forgiven at this price point): 1. Glass isn't very durable, I've got a few chips in mine. 2. OS isn't super stable. I've seen it crash and reboot a few times, but the reboot time is very fast. 3. Watch faces aren't really that great on the market. I attempted to make my own and you have to upload an individual picture for each number, for each position. Who designed that??? 4. AOD will not have the numbers line up exactly with the watch face. This is by design to save the screen from burn in. 5. It should be easier to have maps display route guidance (just next turn direction and distance is all you need). Currently you need to install a companion app (which requires permissions it doesn't need) and if you put your watch down for too long (you know because you are driving...) it will put the app to sleep and you need to go back in to open it again. At the very least, remember what app was open and open back up to it. 6. Duplicate text notifications. I believe this to be an API limitation from Android. However, you can solve this in software by keeping track of recent texts and double checking they aren't the same before displaying them. I've programmed a system like this before for Twitch's API due to mirror update lag. It's not beyond capability. 7. The companion app (required for a lot of stuff to work) seems to collect and sell your data to offset price on watch. I'm personally fine with this, but you should know that before you buy.

I was wanting to try a smart watch, never wore one before. I really did not want to spend a lot of money on something that I may or may not enjoy. In comes the Amazfit GTS 4 Mini. I saw some reviews online and on YouTube and a lot of people liked the watch. The price was right so I jumped on it. I have been wearing the watch everyday for the last month and have good feel for its quirks and features. Let me start by saying that this is a good starter smart watch. It does everything that most people want in a smart watch: heart rate, workout tracker, notifications, and gps tracking. The app is very easy to use and is intuitive. Here is my Good, Bad, and Ugly. Good: The watch is very light, can barley feel it on your wrist. Navigation in the watch menus is easy and simple. Has a good selection of meaningful different preset workouts that have their own metrics and interfaces. Battery life is fantastic, like really good. Sleep tracking is pretty accurate. GPS work pretty well for a watch at this price point. Watch interface is also good. Bad: A lot of the loaded workout activities are pointless. There is nothing unique to them at all. Some of the workouts have different interfaces and track different metrics but a majority of the workouts just show time, HR, and calories burned that's it. Honestly they could take off like 50% of the workout activities and I wouldn't even notice and I am sure most other people would not care. The hear rate monitoring during workout activities can be a little buggy. Some times I will start a workout and the HR will not work at all, and some times it does not read my HR correctly. To fix this you simply cancel the workout and restart it and usually that fixes it. It really only started doing this about 5 weeks in to ownership. The step counter is also a little bugged. When you first get up and start walking it may not register any of those steps, it probably will miss the first 20-30 steps you take. Once the step counter is active it is usually pretty accurate. I would say this delay in step counting accounts for probably 300-500 steps lost in my daily step count. You really need to constantly be syncing the watch to the app, the watch in my experience really will not sync to the app unless you open the app. The Weather function of the watch is really dependent on you opening the app and it updating the information. How the watch determines which notification it will allow to show up on the watch is just plain stupid. You have to wait until you get a notification on your phone then you can enable that apps notification on the watch. Although this does not work for all apps, some app notifications can not be enabled on the watch for some reason. It will take about two weeks before you will have all the notification you want on your watch enabled. The watch band it comes with is not good for people who have large wrist. My wrist approaches close to 9" and I was wearing this watch on the last hole and it still was not very comfortable. Got a new watch band this is much better. The screen will scratch very easily, there are some case protectors that you can buy that work really well and solve this problem. There are really no Apps that you can get for this watch, the IOS it comes with has a very small app selection to download and none of them are worth downloading. Ugly: The Alexa function does not work very well and I can not figure out why. It will work perfectly fine some times like when I ask her to start my vehicle and other times like when I am trying to unarm my Ring Alarm System it just plain does not work right. For example when I ask Alexa on my watch to unarm my Ring Alarm system she will ask for the code, I will tell her the code and she will then respond with a message saying that you cant play media from this device. I have no idea why this is her response. I go through the same thing when I want to start my vehicle using alexa on my watch, she will ask for the code, I tell her code, and she responds that vehicle has started. It does not makes sense why it works for one thing and for another thing it just drops the ball so badly. I use alexa a lot and I thought it would be neat to have it on my watch but since it is so inconsistent I don't even use it. The biggest gripe I have is that the watch will constantly say it is not connected to phone yet when I look at my iPhone it says the watch is connected. My phone can be sitting right next to me and the watch will say that its not connected to the phone. To fix this I usually have to open the Zepp App. Its really annoying because you will miss your notifications. Also, the range of the Bluetooth between the phone and the watch is dismal. You can maybe get 15 feet away before it will disconnect. Strange because I have some wireless earbuds that have no problem connecting 30 feet+ away. Overall its a decent watch that does the bare minimum I wanted and then a little extra. I have enjoyed wearing it and now see the appeal of having a smart watch. That being said, this to me really is just a beginner smart watch. If you are not sure if you would like a smart watch or not and want to try, this is a great choice for beginners. UPDATE: Returning watch due to a continuing issue where the heat rate does not work correctly when I begin a workout. I am also having issues now with the steps not being counted at all. I could walk over 100 steps and wouldn't count any of them. I think this is because the watch thinks I am still sitting or something. The standing metric of the watched never really worked all that great but it never bothered me but I bet that is the issues with the steps not counting. Not sure if I have a bad unit or not. Watch worked fine for about 4 weeks then I started having these issues with it.

I love this watch and I especially love the battery life. It may not be super fancy, but it does take your pulse and show you text messages, but the best part is that the battery lasts for two weeks or more.

The pros: Good pedometer, good battery (provided you do not access some functions), comparatively attractive, no mandatory subscription, easy to set up The cons: sleep monitoring very unreliable, software not intuitive which is exasperated by no customer support and minimal instructions, difficulty to personalize functions makes it very annoying and confusing. This is my third smart watch. One stopped holding a charge, the next one required an expensive subscription fee after 6 months. Without the subscription, which cost twice the price of the watch per year, the watch was pretty much a pedometer. I wanted something basic this time. I did not want a high maintenance watch, or one that did not function without a monthly subscription fee. Due to medical concerns, I needed sleep monitoring and a relatively bare bones activity monitor. And while the activity monitor is ok, the sleep monitoring is not. Examples of sleeping monitoring - I was reviewing my sleep using my phone, and it was still showing me asleep. Another night it indicated I had sleep thru the night without waking, when I had gotten up to use the bathroom, made tea and drank it, tidied the kitchen and read my news feeds before dozing off again. This morning, according to the watch, I was asleep while I was conducting business on my computer and taking phone calls for an hour. And there is no way to find out how to adjust or correct the issue. Too late to return. Would not recommend this product. Update: THIS WATCH IS WORTHLESS!!! ACCORDING TO THE WATCH I AM SLEEPING WHILE TYPING THIS. AND FOR THE LAST HOUR AND A HALF, WHEN I WAS AWAKE AND WORKING. DO NOT WASTE YOUR TIME AND MONEY ON THIS FRUSTRATING WORTHLESS PIECE OF JUNK. THERE IS ABSOLUTELY NO, I REPEAT NO SUPPORT. I HAVE TRIED SEARCHING FOR GENERALIZED SUGGESTIONS FROM ONLINE SORCES, BUT NONE HAVE HELPED. THIS IS, BY FAR, MY WORST EXPERIENCE WITH A PRODUCT FROM AMAZON!!! AT THIS POINT IT IS ON ME FOR NOT JUST THROWING IT OUT.
