Serious Bike Care
Works great and the construction is solid. It is a bit fiddly and can drip when you tilt it a bit: Practice makes perfect. Also, after many uses, the inner brush, sponge, wipe component does deteriorate. Good news: Park Tool now makes inexpensive replacement inserts for that component. You have to keep in mind, you are using this to erode tough greasy and gritty grime off a metal chain AND the tool still holds up while the softer, replaceable components sacrifice themselves for the good of your expensive drive trains. Really worth it if you are serious about bike care and have several bikes.
