The Smart Band itself might be good in features but it is NOT supported by LENOVO.
The APP which is to be installed in smart phone for syncing with the smart band is developed by a local Chinese developed Hong Jiang and not by Lenovo.
After a version upgrade the Smart band has completely stopped binding with mobiles, I have tried with both iPhone 6 and Android phone, it has stopped binding. Without this functionality, the whole purpose of wearing the smart band is defeated,
I had purchased it for Rs 2500 on Flipkart, but now have returned the smart band and asked for a refund.
