Query: Horrible purchase!

I had two different kinds of mad katz bluetooth for the PS3. They both failed to sustain a charge. The first one wouldn't even charge out of the box it was shipped in. The second one worked for 2 days and then failed to charge. This is a horrible product. I would not recommend mad katz products to ANYONE!!!! I now know why you have to pay a little more for the official gear, QUALITY!!!
