Query: Barely Adequate

if you simply need a charger, this works fine. I used it with two different 650's without a problem. The issue for me is that the coils of the cord are so tightly wound, that it's virtually impossible to use the phone without unplugging it. It's advertised to stretch from 2 feet to 6 feet; you'll be lucky to get it to 3 feet.
