charging cable so you don't have to have two cables from the car's usb outleteasy to set up. (Just + & - on the frequency)nice design
The product name says "for Iphone 4 / 5" when the charging cable from the transmitter is a micro usb and that won'ät fit apple devices unless you have a adapter. However the fm transmitter part will fit every audio device with a 3,5mm stereo jack. and that is about every phone you can think of, so a name edit would be good.
The transmitter works as supposed, you can plug it in on top of your iPhone or plug it into any mobile or mp3 player.The sound I get in my speakers is great, sounds just like it was connected with AUX cable.It's very easy to use, just two buttons to change the frequency of the FM singnal.
Delivers suprisingly good sound.
Very cheap, buy this if you want to use the 3,5 mm jack on your phone.Remember that the transmitter will be upside down on iPhone 5.
