My son uses the Diving Concepts version for his drysuit, I use the Viking bayonet system. I purchased my system at a local meet & greet and prefer them over the Diving Concepts system as they are easier to don and doff. The rings are designed to be aligned and turn about an 1/8 of a turn and you are ready to roll, no need to worry about them popping off under water. Upon exiting the water another 1/8 turn and they are off. I found that my sons rings are a little more of a struggle to doff after the dive, even though you are supposed to be able to use the ring portion from the gloves to pry them loose.
