Samsung WEP410, Anyone have one?

[Hawk]

I just won one on Ebay, and I am curious to hear users firsthand experiences with this headset. I have searched heavily for reviews on this headset, and so far, I have found 1 review with any negative comments. None of the 3 earpieces fit the users ear well and it fell out here and there. The other comment along with that one was that the talk button was in a place where it can easily be pressed while trying to put the headset back in their ear after it fell out.
Anyway, I got it for a steal and just wanted to see if anyone else has tried it.
Here's the kicker: I saw this in the AT&T store for almost as much as the Apple bluetooth, but I got it for nearly a fraction of that price.
