Title: they clog very quickly and easily
Review: I have two of these and they both have become clogged, I haved tried soaking them in everything from vinegar to hydro peroxide...barely any bubbles and it actually fouled up my pump because no air was getting through. Nice idea and design I just wish they would produce for longer than a month.
