My wife and I are on our third season with the Oxygen helmets, and finally had enough of the constant problems with controllers and shields having to be replaced - we're at 4 controllers and 3 shields between our two helmets now. On top of that, we had many issues with the shield freezing up and then being unable to close it properly after stopping on the trail for a break.
I switched to a Mission in December, and my wife did the same in January, we are both very happy with the switch - the Oxygen is great when it works, but for us the number of failures and the frustrating issues with them freezing up on trail-side stops became too much.
