This is the 2nd bluetooth speakerphone that I've purchased for my car, after also owning 4 bluetooth headsets. The headsets don't work for me. I previously owned a Parrot Minikit, which worked reasonably well for over 3 years, then suddenly died -- although it was working, sound could be neither transmitted or heard through it's speaker. I purchased this unit after reading consistently positive reviews, and got a killer price for an open box unit. Here's my thoughts: the sound quality is better than the Parrot on both ends. The Parrot has better volume with the built-in speaker, but using the T505 over my car stereo is totally awesome. The battery life seems to be pretty good. I'm going right now on my 2nd week without a charge using it daily. Pairing is easy. The auto-pairing when powered off and on works quickly and without a hitch. The text-to-speech voice dialing, which is really a function of the phone not the T505, is OK (I'm using an LG Env2). I usually dial out on the phone, and receive calls using the T505. The control layout is pretty good, and the indicator lights are actually useful. The manual is surprisingly well written. All in all, I am pleased with this unit and would recommend it to anyone looking for a high quality speakerphone for the car.
