I bought the band believing the reputation of the brand Lenovo , but the band had pairing problems from day 1 . I tried contacting the company no reply from there side as well. Within 3 months the band stopped charging and I lost my whole money . When you contact customer support they say it’s not a part of lenovo and you can’t visit lenovo service center and the phone number given in the app for customer support doesn’t even reply . Pathetic service and worst purchase . Too much disappointed.
