Review: Good but large smart watch - First off, the seller I got this from was great. Arrived on time. Watch didn't have a single scuff or smudge on it. Literally like new. Box is generic, but everything inside looks original including the charger and the manuals. The battery was a little low (56%) when I got it, so I gave it a charge before set up and it was full in no time. Watch itself is great. Easy set up as long as you follow the directions and use the app. Picked a simple watch face and called it good. The main complaint I saw about this watch is the battery life. I read up before getting it and adjusted settings right off the bat. I don't keep the face on all the time (1. For battery life and 2. Some users had screen burn) I don't care much for the health things, so I have all preferences like the bpm monitor set to manual so I use them as I see fit instead of them either going continuously or every 10 minutes. If you have bad eyesight like me, use the large font setting And for the love of everything, download the Gboard app. Like literally right out of the box past set up, get it. Otherwise you have to use T9 and text like it's 2000 again. The only downside (for me) is I have tiny wrists and the standard band is way too large. There are large gaps on either side. This isn't really a downside, I just had to spend a little extra on a new band. No biggie. Over all, great watch. I may just get my partner one too. (It now has a walkie-talkie app!)
Review: Very good purchase - Love this watch. It does everything I wanted it to do. Just wish the battery lasted longer. You do have to charge it every day.Display is very good and clear. It has a good selection of features. Even though you have to charge it everyday, it charges fast.

### ⭐⭐⭐⭐⭐ Great Watch
*by G***N on March 25, 2024*

NB - Reviewing an Amazon renewed 40mm Galaxy Watch 4. The watch has no defect I've been able to spot. As of writing this, I've been using it for a little over 48 hours. There are some scratches on the rim and at the screw areas, indicating that it's not brand new. Also, it takes around 60-90 mins to get to full charge from a dead battery, and at the end of an 8hr work day, it's at 48%. It can run hot while charging so look out for that. Seems like the heat can drain the charge as well.
