It works but when the system is pressurised, it can be a battle to connect. For what I use it for (off-board gas to BOV connection), it works fine as I have fairly long lengths of hose to play with and I can either connect it on the surface on a larger boat or lie back and fight it on the surface if I'm shore diving or RHIB diving. Once connected, it remains connected until I get out again. For close in, underwater gas switching, it would be ok-ish but I think it would become annoyingly hard work quite quickly. It is relatively cheap though and works.
