I ordered it after my daughter's dog chewed my Motorola HS810. Since it was less expensive, and I read good reviews, I decided to purchase it. The earhook is rubber, nothing like the ilustration I saw in Amazon. It was always falling! Didn't fit snugly. It didn't come with the rubber cap that was suppose to be in the packaging (to hear better). The speaker was over the ear canal, so the sound was poor. But what really upset me the most was that after an ahour, the device disconnected by itself. When I tried to reconnect, on my cel was a "bluetooth signal busy". This never happened with my Motorola HS810. after 3 weeks, I had it! Yesterday I sent it back to amazon. I'm sure it was defective. But I am not buying a Cardo 500 ever again! With the HS810 I never had a problem. When you buy cheap, it becomes more expensive! You wind up buying the better model!Connie
