Review on hygger Bucket-Free Aquarium Water Change Kit: Metal Faucet Connector, Fish Tank Vacuum Siphon Gravel Cleaner with Long Hose (25FT, 33FT, 49FT) - Drain & Fill Effortlessly! by Tim Armstrong

None of the included adapters fit my sink. Can't even test. My sink is pretty standard, not an odd diameter or anything, so I don't think the adapters that come with it "fit most sinks". Now I have to somehow figure out which adapter I need. Pooh. EDIT: One of the adapters is plugged into one of the other adapters and I couldn't see it until I got desperate and was finally able to unscrew it. Oops! Returning a star, sorry! HOWEVER, the faucet head flows like crazy. I'll try Teflon tape next time I do a water change, but that's something to keep in mind when considering this article. You get what you pay for I guess.
