If you are going to advertise this junk, please to a test to compare these things to name brand ones.
For all we know all these watch sensors are nothing more than random number generators.
If you are gonna promote them, get a few of them and do a test showdown.
Yeah from the photos you can clearly see it doesn't even have those sensors. This watch is being sold under many brand names and many have been featured here. It's a total scam of a watch
