Great generic s4 smartwatch – worth every cent! This generic s4 smartwatch is very good for its price. It looks nice, works well, and has all the basic features i need – heart rate, steps, messages, etc. It’s light, easy to use, and the battery lasts a couple of days with no problem. For the price, it’s a perfect gift too – looks more expensive than it is! Highly recommended if you want something simple and functional.

I am really happy with this! Looks great, good build quality and has so many capabilities and customisation options. I didn't know but it actually came with 3 different straps too, metal, silicon, and leather style. I only wish i could pay with it, but am very pleased with this purchase.

This is Xiaomi's latest watch. I opened the package with great anticipation. The watch is great, the screen is very clear, there are many practical functions and very accurate GPS map navigation, but it needs to be connected to an app to be practical. The app is easy to download, and the manual is very comprehensive. It will tell you everything. This experience was great. I will recommend my friends to purchase, it is worthy of your trust!
