I purchased Lenovo HW01 Smart Band through flipkart. This product is cheap quality one but looks good in hand. Band will fit perfectly in hand. Once charged it gives 3 to 4 days of backup. Band perfectly matches with any android phone having bluetooth connectivity. It gives some sort of hands free experience since any sms and miss call details no need to pick the phone. Band will give the accurate value. Band hangs sometime it takes 3 to 4 secinds to wakeup the screen sometimes. Its plastic outfit gives cheap quality fashion. Only if you are ok with cheap rate band then go for it else purchase costlier different band.
This band only provides only basic look and feel of smart watch. I nomallu forget to charge it regularly so offten I face band switched off problem. Heart beat rate scanner gives some what accurate result but cant trust it since it gives different result every time. Activity tracker is just for name sake. If I walk for 100 steps then it shows 130 steps.
