I've had this product nearly a year now and its still as amazing as the day I bought it!
It was easy to set up, it "speaks to you" and tells you exactly what is happening, eg, connecting or disconnecting the phone.
The FM transmitting it faultless but not essential, so you can listen to phone conversations either through the car stereo or the speaker on the item itself which is actually perfectly sufficent!
It allows you to play music through it as well which many in car systems don't, so you can play any music on your phone through the speaker, or FM transmit it to the car stereo! A function I found useful when I only had a cassette/radio in my car!
Apparently it is clear for the person on the other end of the phone, even being mistaken for me being parked (you cant hear the engine) and with the phone by my ear (very clear and loud)
The only fault i can think of is that the clip does dent the sun visor where it is attached but I have moved it and the dents do fade and dissappear with time.
Honestly a fantastic product and my friend spend a lot on a parrot brand one getting it installed in her car and has admitted that this one is better!
I love this product, all the functionality and it looks snazzy too!
