Pros: I love this little device, so much so that i got one for my GF. Works well, pairs easily and transmits well on FM. Sometimes (specially if you are in a city) the FM signal will waver, but I recently used it on a 300 mile road trip and I did not have to change it once.
Cons: None really, well yeah. Would live for it to be able to pair to two different phones at once.
Summary: I loved this device so much I bought a second for my dad.
Pros: 1. The FM transmitter is very strong. Other reviewers complain that the transmitter was not good, but I find that mine can even overpower weak radio stations. I have a Monster FM transmitter, and it is not nearly as good as the T505's. 2. It automatically finds new stations for you to broadcast on. Very simple and easy. 3. The voice-activated calling works great with my Android HTC Evo. 4. The sound quality is great on both sides. People I talk to do not know they are...
Cons: The unit is difficult to use when I have to put down my sun visor. That's not really the unit's fault, but it is the one time it's not safe to use when driving.
Summary: If the FM transmitter worked better, I would give 5 stars. I would place it in the center of the dash (~3 feet from antenna) and would hear lots of static, etc. even from "blank" FM stations. I had hoped to use it to stream audio to my factory stereo, but the weak FM signal makes this difficult. It works great as a stand alone BT speakerphone.
Pros: Small Long battery life Sound quality from built-in speaker Easy BT connection to phone
Summary: We have used this a number of hours and have yet to charge it, I see what it is rated at for hours and believe this will be a nice user friendly device for some time to come.
Pros: This hands free device does a much better job than the bluetooth in the GPS. While the GPS does allow hands free function, the audio and ambient noise pick up are miserable for both ends, worse for the party not in the vehicle. This unit solved our hands free need and works great.
Cons: Wind noise from the windshield of the car was a problem at first but we moved it to the end of the sun visor and now it works much better.
Pros: It looks and works good. YES, you can leave it plugged in all the time, I hid a long wire ($6) behind the dash and window trim up to the unit on the visor. Good battery life but doesn't matter to me. If your stereo doesn't have Bluetooth this is the way to go.
Cons: I agree a simple on/off slider would be an improvement and it is a little funky selecting a FM frequency, but no big deal.
