I bought this product because I used to have a scosche bluetooth adapter many years ago and I never forgot how well it worked so I bought another one. I use it on trips with my roommate and it's very nice. If you want a quality bluetooth adapter buy a scosche you will not regret it.

I bought this entirely for purpose of playing music through an older radio on my boat (ie using the FM transmitter). I have not used it to make phone calls. The quality of the transmission is excellent. I had a very cheap FM transmitter that I replaced with this one, and the difference in quality was night and day. The music sounds excellent and I now have Bluetooth functionality thanks to this device. Highly recommended.

Easy to set up and use. Sound quality is great; so much better than the one I used previously. I haven't tried a call yet but if it's a good as the music quality, I'll give it five stars. So far, highly recommended.

Add hands free and Bluetooth where there is none. I have an older model SUV that is still working great but didn't have hands free, but I didn't want to spend a lot of money upgrading the entertainment system. This was recommended to me by a friend, it works great and does all it says. And while the controls are not exactly intuitive, they are easy enough to figure out. It's not that I don't read directions, it just that with so many gadgets, it's hard to keep up with their operation. And once this is working, you don't have to touch it again unless you need a different FM station to tune to. Also, be aware that if you switch stations, you have to power cycle the unit to reconnect to your phone. But you can just pull it out of the power socket and plug it back in. I've used in several different locations, having to switch stations several times to find a clear channel. The unit itself works very easily once connected. The sound is clear through the car speakers, and if your phone is not too far away, others have told me I come though clear enough to understand. Notifications come through (email, navigation, etc.) also come through quite clearly also. When listening to the radio, switching from your favorite radio station to the phone is easy, just program one of your buttons to the Handsfree station, then if you get a call, just switch to the handsfree station and answer the call.
I do have two suggestions: 1. The buttons on the unit are black-on-black (around the answer button) and are NOT backlit. Suggest you paint them white, or glow in the dark so they are easier to see in low light and you can figure out which one you are pressing. 2. The remote controls works great, but the symbols on buttons on the remote to NOT match the symbols used on the buttons around the unit (again, around the answer button), leaving you to guess which function on the remote does the same thing as on the unit. This is a nuisance thing but don't lose the remote. The remote has some functions that are not available on the unit (understandable), just recognize the difference.
This unit would be great for say a classic car that has FM (or added in a hidden area), because you can add the functions from your phone without hurting the classic look of the car. Also, I don't understand why the auto manufacturers don't get out of the entertainment systems business (I really do, its $$$) and just add the capability to use your phone directly from their in-car displays. It is simply a matter of programming and wiring. And using your "free and always up to date" map and GPS makes a lot more sense than paying the dealer several hundreds (to several thousands) of dollars for their bug ridden and inaccurate navigation systems that you have to pay over and over to get updated. This unit goes a long way to making it much easier to leave out the fancy radio/navigation system and just use your phone instead.

Latest edit. Finally took the time to get a sharpie to color in the buttons, as they disappear in the car. Especially on bright sunny days, as in most autos, this unit will sit lower down, in the shadows. See photos. Rather than trying to color in the depressions, I covered over the flat part of the button, leaving a good contrast. First button is a little sloppy, as I was experimenting. But his seemed to work well to provide a good contrast..

good.
