Hey friends I bought bingo m2 waterproof smart band 5 months ago to gift it to my wife, she still using this band, she had problem in this band was it disconnected automatically from her mobile phone, and also there is a problem with its connectivity, to use this band we have to download a supportive application from playstore that name was droi health, without this application you are not able to set its time and date.
Firstly this band is being so helpful for her for calling on her phone, when she working in kitchen and her phone is in bedroom, she fine out that she had a phon call on her mobile just because her bingo m2 band was vibrating and showing the no. From the call are coming, but now the band doesnt showing the call, and doesnt vibrate on call, its battery was awesome. But just disappointed from this band, I hope this review is helpfull for you for choosing this smart band. Thank you
