Things I liked:The Quick Disconnect works great. What others should know:I had a little problem with air leaking only at the pipe theads, but with a little sealer on the threads ( not much) crank it tight, thereafter,no problems.
Things I liked:Easy to install, and it works without any problems first time. Things I would have changed:The Scuba refill clamp shown in the Airforce DVD has an extra pivit joint than the current one that Airforce issues now. It may have been a nice option to be able to rotate the air tank. But an extra joint equals extra cost and maybe extra place for air to leak. What others should know:Easy to install, doesn't leak air. The one I got works just great.
