I've been using this for a week already and so far I love this smart watch. I'm giving this a 5 star  because of the physical component. It looks decent, I love the strap which is buckle style and the strap fastener is movable. When fastener is movable it helps the strap in preserving from wear and tear and by not creating a crease easily which will break the band faster.

There is a Qr code in the user manual which helps you to download the app for your phone which syncs with the smart watch or you can go to app store or google play and search for smart wristband.
This is easy to use and you just need to get the hang of it to familiarize the functions and features.

It never fell off from my wrist even I am so active at work. This is suitable for people who are on the move all the time. I love this smart wristband form AGPTEK.

I got this a sample.
