Bests & Worsts Reviews from Amazon

I don't like to give bad reviews but I have to speak up about this one..... it almost caught fire. Yup.... i tested the usb port part of the item (which was the main reason why I bought it) as soon as I got it with my phone. Walked away and it hasn't been even 15 seconds when it smelled like burning rubber. (In lucky it didn't mess up my phone) I unplugged it and noticed it (the item) got so hot that the bottom rubber was starting to warp. I let it cool down and tried again and it was the same result... not gonna lie in kinda pissed, this would've caused a fire if I wasn't paying attention.
