Pump works great, perfect amount of fluid in one pump.
This pump has been a money saver for us.  My kids typically use a lot of mouthwash when the pour it themselves.  With this, one pump in a cup is all they need.  Our bottles of listerine last way longer now And it prevents anyone *guilty* from putting the mouth on the listerine bottle and pouring directly in.  Not something that use to bother me, but with covid/flu/strep/etc., no one wants to risk possible reinfections (germs leftover on neck of bottle).  So, the pump is great, we've used it for over a month and it still works great.  I'm gonna get a second one for the other bathroom.
