Actually this is my second M3 band, first one am using is so good with all features and good working sensor. Second one is entirely a different product the seller is cheating us. This just like a kids watch and not working sensor and no features at all. Waste of money buying this product.
5 star rating for delivery in time. Product is fake upon checking , please do not buy this or such imported items .results are misleading.one can check photos captured in which it shows readings even if band is not tied in hand. I have asked for refund and pick up this useless product. Strongly advise do not procure. I also urge Amazon to black list such and other products to sell customers.delist them. Given one star even if not not in mood to rate it as one.
Please note there is no booklet/sheet on setting the default values to the fitness band. The time needs to be set to ensure correct daily monitoring. Also all mentioned features (Bluetooth or Heart Rate sensor, Activity Records, Sleep Monitor, Calorie Burned, Rejected Calling, Alarm, Blood Pressure, Message, USB Charging Supports smartphones, Tablets and PC's and also support Android and IOS) are not available at a a time. Any one can be monitored.
Nott even interested to rate it 1 as it was the worst product to buy. Ot able to insall the app and connection was not happenong to my phone . I have tried with three different phones , also there was a paper inside it , mentioned that please rate the product 5 and get cashback of rs 100 and then return the product if u wish. I. Bought it after seeing the reviews only and now can conclude that people for just rs 100 rated it 5 star . Total waste product .
