I have two that I would sell if interested. They worked ok but the wires were a hassle for our riding style. They've been sitting in the attic for a couple years now just taking up space.....
I used them for awhile on the paintball team but I learned to always have a set in reserve because the PTT would go down. We always had a set in rotation back to the company and would have two sets with us. Pretty much everybody had the same problem. We were able to get a sponsorship from Clearer Communications and their stuff is top notch! You might check them out. They are more expensive than firefox but they will not fail. We put them through the ringer out playing scenario ball and they hold up just fine.
