Cygnett GrooveTrip II Mini FM Transmitter

Does the job perfectly, as long as you select a frequency that does not interfere with any main channels. A simple , yet useful gadget for those who dont have 3.5 mm point in the car stereo. If you are using it for home stereo , you need fm transmitter very close to the system. Overall verdict :excellent product, does what it says on the box.

This is a perfect little item for those people like me who don't have an input slot on their car stereo. The mini transmitter plugs into my phones headphone output, tune the transmitter to an empty channel on the radio and away you go. Provided the channel is really empty then the sound quality is excellent. Really easy to setup. Wonderful product. Battery life on the transmitter is excellent. Would highly recommend this device.

The sound is a little bit biased towards the higher frequencies, I think, and obviously there is some interference unless you can find an empty slot in the frequency band, but it's perfectly adequate for use in a car.
