Title: Only useful on soft clogs
Review: This use a useful (if cheaply made) tool, and it may serve you well - if you only ever have easy clogs. Apparently whatever is blocking my bathroom sink fought back, so that when I pumped it 20 times (on the low end of their recommended "20 to 30") and shot the air down my drain, it blew out the weakest point on my pipes, which was the P trap. I guess completely redoing the drain is an effective way to deal with clogs.Save time, and get a snake instead.
