Itrip Auto Universal

The sound quality okay, not nearly as good as other FM transmitters I've used, even on clear channels. Does not seem to have the power as other transmitters either.

The most annoying this is that it will turn off if it thinks you are no longer playing music. This typically happens to me when a quite song comes on. Because the radio is turned way up to hear the music (my ipod's volume is almost maxed out and this still happens) when this happens you get an earfull of deafening static.

Its a decent transmitter if you know how to switch it to international mode. pretty much hold in the one button on it for like 30secs until you get a choice of US or intl. then you can access the lower frequencies that seem to work a lot better. 87.9 works great for me. The problem is the shutting off when it thinks there is no sound. If you don't want this to happen you got to turn up the ipod volume until it distorts, but who wants that? It pretty much turns off every five minutes for me. So I kinda drive with one hand on it to hit a button to turn it back on at all times. This is the stupidest function its not like it runs on batteries, then I could understand trying to save power. But it plugs into a cigerette lighter outlet, whats the big deal with saving power its plugged in!!!! It should be on if my car is on and thats it. Instead they added a corny function that serves no purpose but to piss off everyone who bought one. Good job Griffin.

Pro's:
1)The sound quality is in-between fair and good enough, the problem is that there is a very subtle static noise, but it's not always there and when it is it is very subtle

2)the size and weight, and the fact that it doesn't need a battery are great features.

Cons:
1) when it gets hot from being in the sun in your car the display becomes annoyingly painful to try to read, so plan on keeping it on one channel

2) it seems that if it get's bumped around it will turn off momentarily, it also seems that when you play soft music, it tends to turn off also, so no opera or symphony.

Summary:
It's a great device for the price I paid. I believe that if the antenna on my car weren't at the back the static problem wouldn't be a problem. I simply gave three stars because of the quality and the fact that it turns off periodically.
