This works great when my car is stopped and the engine is shut off and the windows are rolled up. Even the most diehard people I talk to who are great "bluetooth interpreters" when quality gets sketchy say it sounds like crap. Again, if I'm stopped it's fine, but the microphone is VERY directional, in the end I was just holding it in my hand like a phone and asked myself why? Why am I even using it? Putting my Razor on speaker and sticking it up on the visor works better than this thing. One thing, I drive an Nissan Altima, and the highway noise in the cabin is fairly high. You might do better in a quieter car, but I'll take mine out of my desk and give it to you.
