No problems at all
I haven’t had any trouble with these. When they don’t stick it’s usually cause the valve is still dirty. Clean the valve good and they stick every time. I’ve used about 5 times

Excellent Suction Cup
It's a quality tool. Good suction cups. Should fit the majority of valves out there. Didn't work for my project as the valves are super tiny...like comically tiny. After each lapping, give them a wiping and they should last a long time.

Good but…
These are good, but the rubber falls off mid job. It works, but maybe deepen the rubber grooves or harden the edges?
