I bought what I thought was a Smartfit 2.0. Open sky website said it would accommodate iPhone 6 plus. Took almost a month to get it and what I received was something called a smart bracelet 4.0. The box it came in showed it would work with up to a iPhone 5. When I programmed it, the first day I wore I took it off and wanted to throw it away. The pedometer was counting every slight movement of my hand. I even put it on my non dominant hand. It had over 6000 steps before I even got to work in the morning. I had a fitbit before and it never counted my arm/hand movement. Horrible product. Do not recommend this website to anyone.
