A very clever system. You have to be careful when attaching the gloves, the o-ring will not get stuck in the bend if you attach it too quickly or with force.
Although a basic glove system, for me and my dive buddy works excellent. You just have to be careful with the fast movements of the hand, the glove may come off, happened to me once when I turned off very fast my buddy's cylinder on the surface. I noticed, I replaced it and that's it, I had a great dive!

Work until they get sand into the threads. After that awkward to open.
