Got the job done!
Used these to plug vent and sink while forcing pressurized water through cleanout to unclog the drain line and worked like a charm. Really handy tool to have.

Used once
I used this to pressure test my boat's fuel tank. I filled it to the recommended psi to plug my boat's gas fill tube. The rubber spit. There were no sharp objects. Waste of money and a 30 day warranty. Complete garbage!

but it worked fine and I passed inspection
I would give it 5 stars if the directions had been clearer. I could not get it far enough into the pipe through the test T, so I had to take the pipe out of the stack to plug it, but it worked fine and I passed inspection.
