I used to love this bluetooth headset. I used it for about two years, and loved how quick it was to answer calls by just flipping it open. I also like that you can easily switch it from right ear to left ear by just pulling the hook off.The buttons on this device are easy to access, and it was comfortable enough to use for extended periods of time.However, overtime, the static on the calls just got worse and worse until I could no longer use this without people getting really annoyed. I don't know if maybe I dropped it too many times, or if moisture got into it, but after working well for about a year and a half, I had to retire this device. I now use the H730:Motorola H730 (Bulk Packaged)Even at its best, people could still tell that I was using a bluetooth when speaking with this device. Since upgrading to the H730, I have not had a single person ask if I was using a bluetooth. I think the placement of the microphone hole on the newer version may have some impact on that, as it is away from your face more on the newer version, compared with being on the actual flip-open boom piece that rests on your cheek. For these reasons, I only gave this bluetooth 3 stars, and would recommend the H730 instead.
