The Androids fit well on my Grivel Taakoons. They clip on and off easily. If the climbing is easy, I clip the leashes to my harness. If it starts getting sketchy or I get scared, I put the cuff on. It is important to make sure the part attached to the shaft is exactly the same length for both tools otherwise you’ll have to mark the tools and cuffs L-R. They do come unclipped now and then, but it is usually when I’m doing some shenanigans. The annoying thing is the metal clip gets in the way when placing screws, and it hangs up on rope, slings, or whatever when managing stuff at the belay. Better to take them off when you don’t need them.
