If they are that easy, which I don’t know since I haven’t used them, that maybe how some people have them pop off in use, I know it’s nearly impossible with the ultima, same design concept as the KUBI but obviously much different execution. I doubt I’ll live long enough to try the KUBI since I’m getting up there and I don’t know anyone locally that uses them. I wonder if they have thought of making a suit side ring that would fit the oval suit side, it would expand their market since I would give it a try.
