Pros: - Easy too set up and use
- Sound quality is OK for an FM transmitted signal
- Bluetooth function works well, no feedback or echo and the sound through the cars speakers is clear. No complaints from anyone on the other end of the line
- works well with SD cards and USB drives
- it remembers what song you were listening to when it is unplugged starts than song again when you plug it back in

Cons: - sometimes I get a small shock from the small metallic jack on the side when I insert it into the cigarette lighter
- screen that shows the song title and artist is far too little to read while driving
- MP3 player does not appear to support random play or folders, it can get tedious listening to the same songs over and over in the same order
- I wish it had an input jack to also play my satellite radio through it

Bottomline: Works really well for a bluetooth interface with your stereo. I think this works as well as the one that is integrated into my Prius as a factory option. Lack of features on the MP3 player are the only downsides.

Pros: - Excellent quality of sound (it seems like a real FM broadcast)
- Full FM tuner range. So you can select the best frequency for sound quality improvement.
- Excellent mic quality (for handsfree function)
- Intuitive interface, that makes it easy to use during driving

Cons: - Does not have shuffle function, so you must listen the songs in the exactly order you put it into the memory card
- The remote control only works in certain position, making it difficult to use during driving

Other Thoughts: - It should have an option to light the panel only when any button where clicked (the way it is, keeping the lights on for all "use time" makes it annoying)

Bottomline: It´s an excellent handsfree apparel, with excellent quality of sound (even receiving or transmitting it), simple to use and very intuitive.

Pros: This gadget is an absolute must in California, since it's a law to be hands free with cell phones now. It does everything it's advertised to do, I love the small remote controller that came with it. I makes my 95 camry feel as though it's rolling with the cutting edge technology

Cons: You need a good radio receiver, I've tried these in cars that have junky radio receivers, and likewise the sounds quality sucks. Luckily for me, my car has a great radio receiver and both music and phone calls work awesomely.
Another con, is you can't control where the songs start, I wished there was some sort of file organization that can be seen with the LCD

Other Thoughts:

Bottomline: This product is simply the best for bringing your low tech car without bluetooth to the modern world. With it, I can make calls and talk to my friends and family all with a push of a button.
