A horrible hair-clogged bathroom sink led me to search for a better drain cover. Tub Shroom was the only thing I found that seems specifically designed to solve the hair issue. In one week I could see a considerable amount of hair it had prevented from going down the drain. Problem solved!
I ordered three; two for bathroom sinks, and one for a bathtub. It didn't fit on the second sink due to the built-in drain plug mechanism.
A small improvement to the design would make it a five-star product for me. I'd like the decorative cap to be more securely attached. It often pulls off when I am lifting the plug out of the tub drain.
