Been using the Platinum 900 for about a year now. System works well and is easy to swap between helmets if you just tuck the wiring under the padding and have the velcro mount patches already in place. The system really isn't that great for music reproduction, but for voice its very good. Mine came with cords that didn't quite fit into the jack recepticles so I had to shave them down just a tad. I have never had a problem with the cords coming disconnected, very tight. The battery life amazed me, quite frankly. We never go more than a few hours per day, so I didn't have to recharge until after the third day... 8-10 hours I'm guessing? This is not the Cadillac system, but at $200 it's great for voice, functions well, and is very versatile. I have not tried to use it with a tranceiver for bike-to-bike, however.
