Summary: I've had 2 of these. The first worked brilliantly then after about a year or so it just stopped working, I thought for $90 it'd have more life in it. None the less i was happy enough to fork out the cash for another one. The new one has been working for about 6 months and now has simply decided to work intermittently some days i'll get perfect uninterrupted sound.
Summary: This one works well with my gen6 iPod. Can automatically scan for a FM channel that is open or weak enough to allow your iPod to play back thru the car's radio. A great feature when driving a long distance. Cable length is enough for me to route it in my center console keeping the clutter down. The 30 pin connector is very similar to the standard Apple cable allowing easy plugging/un-plugging. Good sound quality.
Summary: This works great I've had several over the years. My last one quite working after two years I guess that's not too bad. I love it for my 4/4S but am thinking about buying an IPhone 5 and wonder if it will work with that one. Otherwise love it. Oh by the way I live way out in the country so I don't know about big city use but where I live and the medium size cities around me it works great.
Summary: Not clear about all the bad reviews. Mine has worked great right out of the box. The app on the iPhone quickly found two great frequencies that work. Yes, there is a little static when no song is playing, but it is a transmitter so you have to expect a little! I rarely hear the static when a song is playing. I've had 4 brands of these and this is by far the best one.
Summary: My other half bought this for me as the cd player in our car isn't working. This one was recommended as being one of the best, most powerful (and most expensive - cost is $100.00 where we live) one on the market. The sound is terrible, really static-y and I spend the whole trip driving around constantly searching for a "better" station and never finding one which is incredibly annoying.
Summary: Bought this is June and it worked fantastically for about 4 months. Then it started getting super static-y all the time unless you were driving on VERY open highways. It got to the point where it started cutting out a lot, even if it was on a 'good' station. And then today it just stopped working altogether. I have no idea why. Anyway, it only lasted me 7 months, which was a disappointment considering its price.
