BESTEK 4 iphone FM transmitter car ipod car FM transmitter mp3 player wireless FM transmitter usb with remote control SD / MMC card slot + USB stick + Audio input jack, mp3 FM transmitter car kit for iphone 4,3gs&3g,ipod touch.Nano,Classic S650
I bought one of these, and it worked great for 3 days, so I bought another one for my other car.  Both of the audio input jacks broke within the next 48 hours. I bought a 3rd party jack because I figured this product was such a great deal, even if I had to spend another dollar. But then both of the transmitters stopped working as well.  Returning both, very disappointed.
