Great!

This device works really well. Unfortunately it doesn't fit other iPods (like iPod Video or the new nano) but it works with my nano perfectly! It does suck up the battery life of my iPod pretty quickly, but I have yet to find a radio transmitter that doesn't do that.

Bigger than what I expected, but works well

This is actually my third iTrip that I have purchased (each for different iPods). I have always been very impressed with the two previous iTrips that I've used. The biggest surprise for this time was that I had expected the iTrip Nano to be a small, tube shaped devise that attached to the bottom of my Nano. To my surprise (and in contrast to the photos shown) the iTrip Nano actually is about the same size as my 2G Nano iPod and slides in up behind the device. At first I was a bit annoyed with the much larger than expected size, but after reading some reviews on the smaller FM transmitters, I changed my mind on the iTrip Nano,. Despite it's larger than expected size (which means I have to take my iPod out of its case every time I want to use the iTrip), the FM tuning strength is excellent. Ultimately, it is the sound quality that is the most important factor, not the overall size.
