Review: Great deal and works great! - The watch arrived in perfect condition. It was renewed but looks brand new. When I first received the watch, it didn't want to charge. I would have to shift the watch on the charger to get it to show charging and then it would discount after a few minutes. I contacted the seller, Chubbiestech, with the issue and they responded immediately. They sent a replacement charger and it works great. The last couple of days has been spent customizing and loading apps and very happy with the Galaxy Watch 4. The functionality is excellent. The screen responsiveness is terrific. I have ordered lots of desertcart Renewed and always happy with the price and quality. BTW, the pics are with a screen protector and bumper guard.

### ⭐⭐⭐⭐⭐ Really great watch overal, but battery life should be better
*by J***H on September 22, 2022*

Galaxy watch 4 40mm. First item bought as renewed by amazon and it really was as it were new, not a scratch on it and everything works excelent, actually the watch has so mamy features, it really is a great overal watch. My only "complaint", (and I already new about it) is that the watch would have been perfect if the battery life was longer. You have to charge it every day, if you are cool with it buy! It came with the charger too. I recommend it if you dont mind the battery life of a day or a day a a half at most.
