Query: It broke

The first time I used the charger it seemed to work fine. The second time I used it it didn't seem to be charging, the plug wouldn't stay in the socket. Upon closer inspection it appears that the plug is loose and just jiggles around in the unit. I sent it back for a replacement, thank you Amazon.Otherwise it is a nice compact size and that fact that the plug folds in is nice.
