    • 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!) ... show more

    • 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.

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. ... show more

    • Battery Dead/ Then Alive!
I came back here to edit my first review....Was WAY to hasty. First day it arrived I charged it up to 100%, within the first hour and 30 minutes it went down to 36%...That concerned my very much and I assumed battery health was depleted and not as advertised. BUT to be fair, the set up takes a little bit, I had a update, and a backup as well from my old watch so I'm assuming that took most of the juice out of it. Today is day two with the watch and it is at 55% at 4:43pm after being on since around 7 am, so night and day difference. I will update this as time goes on just in case things change, but so far so good today! Review Edit a few weeks later: GET A OFFICAL SAMSUNG CHARGER immediately after purchasing. Comes with a third party charger and it was overheating almost every single time I had to charge it, resulting in having to take it off on and on to get it to a full charge. Luckily I had a few left over from the watch I had prior to this, and it fixed all the problems. I can leave it on all the Samsung charger day and night and no warning of overheating or anything. Overall I love my watch. ... show more

    • REFURB SCAM
Purchased a refurbished watch in excellent condition to replace the Active2 that I'd had for years. The watch seemed to work great at first. But just after the 90 return window it started having issues charging. It would show low battery after only 10 hours. Since I have another smart watch I switch this one out with, so I can monitor sleep, it didn't seem like a big deal. Then it started randomly powering off during the day and when I'd get it back on the charger it would show that some battery life was still remaining and I could turn it back on. After a few week though, it stopped even doing that. Now it will start to load the intro screen and freeze. I did troubleshooting with Samsung and they recommended I contact the seller. I messaged the seller and have yet to get any response. This was a crappy refurbishment that was patched for just long enough for the buyer to not be able to return. ... show more

    • Laggy, charger died instantly
Watch is acceptable quality and affordably priced. It overheats easily and often lags pretty seriously. It also requires a full charge just slightly more than once a day, which is irritating. Most frustratingly, the charger that comes with it broke within 4 days of use. Generally not sure I'd recommend the watch as it doesn't really provide any meaningful functions that aren't already handled by a phone beyond a slightly more advanced sleep measuring function (which is frustrating because it often needs to be charged before you sleep anyway) and BPM heart rate measurements. ... show more
