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.
