I have to say, this was a shockingly good experience. I have had mine almost a year when I lost it. I found it the following afternoon, in the parking lot at work. It spent a day and a night on the ground in the rain and even got either stepped on or driven over, as the earhook was broken off. The unit still worked! It would wedge into my ear and I could still use it very easily-albeit uncomfortably. Why not 5 stars? Because the ear hook pivot/swivel loosened with use to point where it would fall out of my ear. I replaced with a 350 due to budget, I wanted to get a 655 but we'll see how this does.
