Today, I grabbed a quick snack at Starbucks and noticed this wireless charging system. So, even though my phone did not need charging, I had to try it out. I decided that it was good in a pinch, but it did not charge quickly enough to consider using it for a long time. It lost contact too much. I think that if you are out and about and your are low in power on your phone, this is a good option, but not for use on a regular basis.
