be aware this is large very large read on [SEP] i was looking forward to using this pump rather than taking the cover off the listerine bottle every time to use it although the items was as described which had no dimension listed only that it fit either the or liter bottle of listerine only i had no idea how huge this would be once attached to at least a one liter bottle the pump goes approx inches above the lip of the already large bottle with no options for use on smaller sized bottle i already had a ml bottle which is about as large as i would want at the bathroom sink but i had to go out and find a liter bottle or larger in order to use this had i been able to purchase one that fit the pint bottle i would be far happier to add insult to injury amazon prime would not sell me the l bottle once i tried to purchase it the product became a prime fresh product which is a service i do not use just be aware this is not a dainty bottle on your bathroom counter sink once attached it looks like a commercial sized bottle would not re purchase
