I have been using the HS820 for a while now, as have three of my co-workers and my fianceé and her parents. We have had very good luck with it. I like that it is small and light. You forget you're wearing it. I have banged my desk phone handset against it more than once. That'll make your ear ring. The sound and voice quality is good. The price is also the most reasonable of the Moto BT headsets.

The cons: The mic is a little far from your mouth but that is a trade off for its compact size. The mic tends to be very sensitive to wind noise. Do not drop it too many times. Two of us have and the volume buttons are rather delicate. They press against tiny little plastic tabs that control volume. One of those broke after a drop. Same thing happened to a friend's. (Yes, I took them both apart.) The battery life is much better than BT 1.0 but not as good as BT 1.2. I charge it up every night and it will last me all day without any problems. It will go dead if you do not recharge it every few days, even if it is powered off.

One really crappy thing is that once you pair your BT headset with the V551, or any other Moto phone for that matter, you will lose all MP3 and MIDI ringtones, and distinctive rings. It will default to the generic Moto ringtone. There does not seem to be a way to get around that. I had that with my V505 and now with my V3. It sucks because I can't use my favourite MP3 ringtones and my BT headset at the same time.

Overall, it is a good little piece. Amazon has it for $45 in Hematite Gray so if I dropped mine into the toilet today I'd probably order another one. $54 CDN is pretty good. Screw the GST though!
