I bought this about two weeks ago and it was fabulous. I had a hole in one of my pipes and I plugged it up and it stopped it within a half an hour. I would definitely recommend it again.

Performed as expected.

I've had my toilet bowl fill up pipe snap free that stopped the toilet from re-filling after the flush. I used this epoxy to effective fix that back in place and it has held well. The condition was wet (but not high pressure) and the epoxy did the job as intended.
