A very basic tool that works great for it's intended job of hand lapping valve's. The suction cups work very well and are firmly anchored to the stick. Make sure your valves are clean and suction cup is wet and you will have no problems. Negative reviews are from user error, the tool is well built.

I needed a suction cup on a stick to removed hard plastic from a sign. Worked perfectly.

This tool is more than adequate to get the job done. I wasn't exactly sure what size cups I would need so I purchased this set and was glad I did since I needed both.Only complaint is the cups tend to slip on the handle but some adhesive should solve that problem.

Couldn’t stay on the valve. Most annoying tool I’ve ever used. Go to Home Depot buy a stick and suction cups and make your own. It’ll be better or the same thing.

I don’t know who has a toilet this small- but these did not unclog my toilet- J/k good material didn’t come undone from the valves during lapping

Kinda obvious, but won't stick to oily or burnt on build up and slides off if not exactly centered. I know, we should clean the valve better but fixing small engine, not building a race car. Ended up using a drill on the stem Also be sure to get all the used compound off of head or your gonna ruin the cylinders .
