Anyone try the Teth Air system. Really like the idea. I've rode my sled several times and when I went to un hook I discovered that I was never hooked up in the first place. I was concerned at first glance that is would crap out on me 30 miles from the truck but it is a very easy instal/disconnect and very easy to turn off. Doesn't effect the kill switch or stock tether system which both remain operational when the Teth Air is installed. Any one use one? How does it work?
