A Smart watch works with bluetooth connection from smart phone. If requries an Ios/Andriod phone to get connected because an app should be installed and way of using this watch is user friendly. Most likely where it is cheap in price compared to other similar watch.
Its built quality is good for the price we brought and much lighter than compared to other watches like ( check out in Aliexpress, Paytm etc) these websites shows.
Its has good option were can text, call, and Alarm, Music, stopwatch, Pedometer and even Anti lost. These good things to have in a watch.
Coming too battery backup its good it stays for two days if your no conneted to mobile and not receiving or dailing calls through that damn sure it stays for two days. Bcoz ive already check it. And if your connected and using for calls and music it stays for only 2 or 3 hours max.??
Touch response, its average if give rating from 1 to 5 ill give 3.
Finally the watch is good and lighter and reliable and affordable.
