Review title is Pretty pumped about this product! [SEP] I discovered the joys of pumping mouthwash at my dentist's office. I guess I'm pretty lazy, as the thought of increasing the cap, pouring, and screwing the cap back on has kept me from using mouthwash for years. But now, I simply push on the pump and I'm in business. The pump is nice and puts out the right amount of liquid per pump. Two things: As everyone else has mentioned, this is labeled as a single use item. I have not followed these guidelines and continue to use my pump. Also, as others have stated, this does not fit the generic/walmart brand bottles. I bought an expensive Listerine bottle, only to accidently throw it out! DOH! So now the pump loosely hangs over my generic mouth wash. That's okay.. I'm hoping no one knocks it over. With those two warnings/caveats, this pump works very well, and is worth the money.
