Review title is 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 &#34;as described&#34; (which had no dimension listed, only that it fit either the 1 or 1.5 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 2 inches above the lip of the already large bottle, with no options for use on smaller sized bottle. I already had a 500 ml bottle, which is about as large as I'd 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 500ml (1 pint) bottle, I would be far happier. To add insult to injury, Amazon prime wouldn't sell me the 1 L bottle. Once I tried to purchase it, the product became a Prime Fresh product, which is a service I don't use. Just be aware, this isn't a dainty bottle on your bathroom counter sink. Once attached, it looks like a commercial sized bottle. Would not re-purchase.
