Query: Pump not sealed properly

A couple things worth noting about this:1. It is huge. MUCH larger than your typical soap dispenser. That may be a plus or a minus, depending on what you're looking for.2. The pump mechanism just slides over a tube of sorts (it is not actually attached to the screw-on top). This can lead to poor suction when pumping since air seems to leak in if the angle you're pushing isn't perfect. I get bubbles and sputtering from it as often as I get soap.3. The base at the bottom, screw-on top and pusher-thing are all made out of that grippy, porous kind of rubber that absorbs dirt and grime. Not too bright for something that is going to be used by folks with dirty hands.I bought it mainly because I've been happy in the past with KitchenAid products, but they really dropped the ball on this one. It is not up to their usual standards in either design or build quality. I would not recommend this product.
