Challenger Smart Band CHG304E Challenger Smart Band CHG304E. The fact you can't find them on Google tells you they are hiding for a reason. POS doesn't even see Bluetooth let alone connect. Zero support. AVOID.

Never came with charger I was upset… Never came with charger I was upset about that should of told me or I would of save more money to get a Samsung one or Apple that comes with charger now they spec me to pay more for a charger

Bought this watch not realising needed… Bought this watch not realising needed special charger. Ordered charger and 3 weeks later received an mini electric toothbrush. Tried to resolve this but no answers, NOT IMPRESSED. Will not be buying from here again

It does count steps well It does count steps well, but that is about it. The battery capacity is very weak and I have to charge it every night. Biggest drawback is that it does not measure heart rate, blood pressure or oxygen correctly. Heart rate and blood pressure are always too low and oxygen level is always too high. I have precision instruments to compare the watch with. I also found I had to resync the watch every time I charged it with the ProFit application. And the print on the watch is too small to read any of the messages receive. After two weeks, I have put the watch in my drawer, it just was not worth the bother.

I ordered the watch and when I got it I ordered the watch and when I got it. It recorded the first night of sleep and then quit after that and now the step counter isnt working and it is constantly coming off of my wrist i have connected it to my phone several times and reinstalled the app and still no sleep data and no steps now
