  • Great Watch
I love this thing. It paired quickly and easily with my S21 5G Ultra. It remains connected and it lasts longer than me wife's apple watch plus it looks a whole lot better!

  • Love it!
I love this watch. The price was cheap. I know it will stop taking updates after this year but I wanted to try it out to know how well it works with my samsung galaxy s24 ultra. It works great. It looks nice too. Everything seems to work great on it and works as it says it would. It's easy to figure out the apps. Calls, texts, notifications come through great. I do have to charge it before I go to bed each night so the battery doesn't die in the middle of the night. Mine charges within an hour when it's down to 20-30%. It is comfortable on my wrist. The size is perfect to see all without having to squint. The accuracy of all the apps is also great. I'm pretty satisfied and happy with it and will buy the newer one soon enough. ... show more

  • Nice choice
I bought this watch two weeks ago So far no issues with it. I have a Motorola phone and had no problem with syncing watch and phone. Size is nice, and battery life is good So far I am liking it.

  • Happy Samsung owner
I had purchased a Samsung 2 from different seller. The packaging was ghetto and it didn't even work. I was skeptical about trying again renewed however I didn't have the money to purchase new. I am happy to say the packaging was great, extra charge and power box. Clear instructions if I decided to return. The watch looks brand new! No scratches or any damage. New band, I'm so glad I didn't give up, I will post another review once I have had it for a few months. I love Samsung watches, my previous one was old, Samsung Active. So having the option to buy the 4 renewed is a win win for me. I have no complaints. ... show more
