Wouldn’t recommend it to anyone! Not only does the product look very cheap but it functions as the same way!
First of all , there is no user guide at all and you dont know anything what you are supposed to do.
If my grandpa had bought this himself, he wouldnt even understand he is supposed to do.
The Backlight is very very dim and there is no option to increase the brightness
For the price it is being offered, I think there are lots of better heart rate monitors in the market , and before someone asks , no the seller doesn’t reply at all!
