Pros Connects easily to Gen 5 Ipod, No need for seperate batteries.
Cons Poor Performance
Summary I used the I-trip with my Gen 4 Ipod and it performed beautifully. That unit attached to the top of the Ipod. With the Gen 5 Ipod, accessories like the new I-Trip must be connected to the dock connector on the bottom. This new I-trip performs poorly. The range is less than 10 feet and the signal is poor and easily blocked. I had to set the I-pod and the attached I-Trip on top of the radio and the signal was still poor. With my previous Gen 4 I-Pod and I-trip I could set the unit 20 feet away and send a clear signal to two rooms simultaneously. The new I-Trip also shuts off the I-Pod's volume control. After trying two different I-Trips I returned them and tried the Belkin unit. It plugs into the earphone jack with a cord and it's not as compact as the Griffin unit. The Belkin also requires 2 AAA batteries, but it's performance is excellent. Considering the battery life of the new I-Pod, using seperate batteries is probably a good idea. I only use an FM transmitter in my office. My home and car are both hardwired. In fairness to Griffin, the problem may be with the I-Pod arrangement. Apple should have left the top connecting design alone. Also the tech support people at Griffin were very helpful and accessable. Hopefully they can work out the bugs.
Pros Digital display, usb passthrough, light, compact
Cons Signal so weak, it's borderline useless
Summary I used to have a 4th generation ipod for which the griffin itrip worked incredibly well. When I decided to upgrade to a 60 gig 5th gen, I didn't hesitate to get the new itrip which was compatible with the ipod I bought, figuring it would work just as well as my old itrip. Boy, was I wrong. This thing's performance is so lousy that it's almost as if griffin didn't hear about video ipods until they started shipping, and they scrambled to put this thing together in a day or two. Unless there's some sort of mechanical limitation in the design of the new ipod with having to use the dock port and all, I really don't understand how they could have tested this thing and been satisfied with the results. It's really that bad.
Pros variable FM frequency selection, fair sound quality
Cons short range, sometimes doesn't power up with ipod
Summary Have been using it or 2 weeks now in NYC and works fine. Interference is the major issue with this unit, but I have it 2 feet from car antenna and works great. For the price it well worth.
Pros I use this product all the time because I can't stand the radio. It's nice to be able to choose what I hear in the car without a bulky cassette adapter.
Cons Where to begin... It drains battery like nobody's business, it often has a hard time overpowering static, it was expensive.
Summary Don't buy this. At least look into the Belkin version before buying this product. It's pricey and it does a very poor job. The interference, even on frequencies with no competing stations, is annoying to say the very least. The idea behind this is brilliant, but this particular product is not worth your money.
Pros Compact and convenient
Cons Interference, delicate to tune
Summary The concept is great but the product is so sensitive to interference that I spend all the time turning and moving the device. In the car, it requires constant and minute adjustment. As a result sound quality is just awful.
