I think it definitely is worth the money if you have a big tank or multiple tanks. If you just have a small tank, you might want to save the cash and stick with buckets. Sometimes they just don't work that well with small tanks- I've overfilled quite a few 10 gallon tanks because I couldn't run to the sink fast enough to get the water shut off. LOL. Most brands have a valve you can shut on the hose, but I never use that. Anyway, just something to think about.
