This is a nice and light weight fitness tracker that I found easy to operate and connect to the free App that you get with it. You do need to download the App 8SPORT from Google Play or the Apple App Store depending on the device you want to connect with. I tried to connect the smart Watch to Android and IOS devices and had no problems with either.

Once synced with your phone the watch will use the information on your phone to set the date and time. There are various settings on the smart watch but I found it much easier and simpler to access them on my phone. To charge it you need to remove the main body from the wrist band and slot it in to any USB. It took about 2 hours to charge and this charge lasted for about 5 days.

The wristband and buckle seem reasonably well made and feels comfortable when wearing it. It is waterproof to IP67 so not only can you wear it in the rain you can wear it when swimming under water. It will vibrate to alert you if your phone receives a phone call, text and SMS message such as Facebook, Twitter or WhatsApp.

This fitness tracker can monitor your activities, heart rate and sleep. It has all the functions that you would expect from more well known brands but is at a fraction of the price. I have no problem recommending this fitness tracker.
