Great product! You need to get the rubber a little bit wet in order to get a good seal, but it worked perfectly for my projects!

They are a little cheaply made, but they were a cheap price.. they did the job.

All in all great product. I was able to lap my valves with this prior to reinstalling my cylinder heads

I have tried this style of suction cup valve lapper before and never had any success. I thought maybe I was just using a bad tool before, so I tried these out. They don't stick. At least not on Suzuki motorcycle valves or the valves in a Honda Accord. I think they might work if the valve face was perfectly flat, whereas the valves I'm trying to work on have a bit of a dip in the middle. I don't know, I'm not a scientist. All i know is, they didn't work for me and I ended up just kinda spinning the valves with my fingers on the stems and grinding in the lapping compound that way. If you're valves aren't perfectly flat on the face, I wouldn't bother trying these.

Good tool, has various sizes for different valves. I used it on a small engine and used 2 sizes. Worked really well.

These suction cups actually work.
