Last year I wanted to have a fitness band so I bought timex ironman move x20 from a online store. I bought this product just because of it's cheap price and looks.
Battery life - This is the worst part of this fitness band. Battery backup of this band is just pathetic. It goes down very quickly. Also it takes too much time to charge again.
Features - it has many features like heart beat sensor and distance calculator but the problem is it always gives their worst. It doesn't even calculate heart rate and distance property.
Biggest drawback of this fitness band is it's too hard to repair.
