Review (1/5): It's a pump....but more for drinks not mouthwash.
Yes, it is good quality, but it is big. The bottle is big so it makes sense....
My major issue is if you gently tap the pump you get a lot of mouthwash. If you don't you get ALOT of mouthwash. I only need 20 ml!
It reminds me of those taps at bars! Or a ketchup pump. Probably work on a keg.
