Want to move the PopSocket? Simply detach it and stick the PopSocket onto a different case. This works best on a plastic case without texture. If you want to charge your phone wirelessly, you simply remove the PopTop. This is the top round part of the PopSocket. If you have multiple PopSockets, you can easily switch out the PopTop for a new design.
