I took my Moto Krave back yesterday & exchanged it for a G'zOne Boulder. My Krave starting acting crazy while I was typing messages it would just start entering stuff on its own, and then started cycling through the ringers by itself from the home screen.
Was going to exchange it for another one, and the other 2 they had in the store were DOA out of the box, wouldn't even turn on with a charged batt. So far I am pleased with the G'zOne. I had PTT activated, but haven't got to try it out yet, as I don't know anyone with it, LOL. But got it just in case.
I hope it lives up to the hype as far as being tough. We'll see.
