Query: not happy at all.

I am really disappointed with this product. The 1st time my sone plugged in hsi SanDisk Fuze, the female part of the plug melted. Luckily we were able to disengage it from the Fuze once it cooled. The 2nd charger I purchased after 2 uses 1 of the male prongs fell out. So, I will be going to another retailer to purchase another charger and hope it works.
