this review title is: pretty pumped about this product and the content is: i discovered the joys of pumping mouthwash at my dentists office i guess i am 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 am 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 is okay i am hoping no one knocks it over with those two warnings caveats this pump works very well and is worth the money.there are other information for this review, one is this reviewer did purchase it and the other is 5 people think this review is helpful.
