Easy to install, solid performance. It just works!
I have two of the earlier models with the little 3.5mm pigtail on it. My son-in-law is always borrowing mine and "forgets" to return it so one is for him and one is for me!
Best solution if your car doesn't have Bluetooth connection. Easy to connect and pair. The only problem I had was that it took almost 8 hour to charge the unit to make it work.
