IWOWNFIT i6 Fitness Tracker Smart Wristband with Deep/Light Sleep Monitor and Call,Text&Calendar Alerts,Steps Distance Track Calories Counter Activity Touch Screen Bracelet (Blue)

This was advertised as a i6 but when I installed it it said it was a i5. I purchased it to replace a i6 that I had lost so I am disappointed that this doesn't have all the features that the i6 had like the heart beats per minute other than that it works well .

Nothing it went on the fritz from the start, quality was really bad
