Review: Does everything and does it well. Amazing watch! - This is quite simply the very best smart watch I've ever owned. It doesn't just beat the name brands, it far surpasses them. I've owned 2 Samsungs, Garmin, Google and a Fitbit. Nine of those even remotely compared to this. I've owned it for about 8-9 months now and it never ceases to amaze me how much better it is than Anything else I've ever owned. Battery life is incredible. I typically get about 3 solid weeks before it needs charged. All the measurements it records (steps, distance, heartbeat, blood oxygen, etc are accurate and precise. It's indestructible and it looks good too. I have absolutely nothing negative to say about this amazing watch.
Review: Durable and bright - I switched from an Apple Watch to the TRex. The main reason I wanted to switch was battery life. The Apple Watch at best could get 24-30 hours, but general use 24hrs was my average. I looked at the Garmin Fenix 8 but I really just didn’t want to pay that price. I watched review after review and felt the TRex was the right fit for my needs. Concerns before I purchased: - messaging - calls - no Speaker I have had the device now for about 45 days. Durability - this is a solid watch. I have been doing a full kitchen gut and remodel. I have warn this watch the whole time and it looks like me. No scratches or evidence of any damage. Battery Life - I think confidently 18 days is consist. The first few days I was messing with the settings and looking it over a lot so battery was only 10 days after charging to 90%. I think you could get even more if I turned off notifications and brightness down. Navigation and menus - the OS is really smooth. Very fast to respond. I like the mix of buttons and touch screen. Especially when you have gloves on and such Insights and Health - I think it is far more accurate on steps than my Apple Watch. I wore both watch’s on the same wrist for a full day and I never realized how many non steps my Apple Watch was picking up. I was sitting and typing at my desk. The Apple Watch picked up a nearly 100 phantom steps. The TRex picks up stress pretty well. It notices when I am thinking about a topic that is stressing me, like “is my flooring going to arrive in time?” Or “we only have x hours to complete this before the contractors are here!” Lots of good health habit reminders and such. I am looking forward to getting more use out of them once this project is over. Price, quality, and worry - when you have an expensive watch you worry about damage. It’s not to say I don’t worry about this watch, but when it’s 1/3 or 1/5 of the price of the other watches you looked at, it’s nice to be able to just enjoy it. Lots of compliments on its appearance and screen brightness. A lot of watch for the process The gaps: I do have moments I wish I could do a voice reply to a text or quick reply, but Apple doesn’t allow that. No speaker is a kind of a bummer and I typically don’t pair my headphones to my watch, but that would be nice to be phone free for a run or workout. Overall, I really like the watch. I thought I would miss the Apple Watch integrations, but I don’t. The TRex still has the camera remote and find my phone features. I don’t really notice anything yet that I miss from my Apple Watch that I would say is a “send it back!” Thing. Updates are fast and so far little tweaks will continue to improve it. I would by it again.

### ⭐⭐⭐⭐⭐ High quality and full-featured.
*by B***E on April 14, 2026*

After nearly a week of use, I love this watch. It's not very large or heavy, so wearing it non-stop is a breeze. The companion app, Zepp, works very well for tracking your health and workouts. Being that I wanted something more durable, the build quality is excellent as is the battery life. I lose around 5% charge per day, which is very acceptable. Watch face options are plentiful. In a nutshell, the best smartwatch I've owned. One I can recommend.
