This is exactly how an on-line transaction is supposed to work.  Effortless ordering.  Extremely quick delivery.  Product exactly as advertised.  Could not ask for more.

I bought this on a lightning deal. So far it seems to be working the way it should.

Product works just as it is supposed to. Also, I'm seeing a doctor to make sure that I'm using it correctly.
Use when needed.

It works.  It ain't pretty.  It ain't perfect.  It works.

First, it works. It works just the way it was intended to work.

What they do not tell you is that it is an air pump, not a water pump. It builds up pressure in the bottle you attach it to (a plastic bottle will bulge a little), and lets the air out when you release the pump plunger. I am not sure I would have bought it had I known that. But it does work reliably. The one caveat is that one must really push hard on the down tube (the one the water comes up in) or it will fall off during switching water bottles. Not a big deal, just letting you know.

Personally, I prefer a water pump to an air pump. The amount of air compression involved in a nearly empty bottle is significant.

These orders go out to my customers and i have YET to get any complaints on them. Being on this end of the situation, it's very important (how people feel about their product) so when i tell you "it does the job", you can bet i'm being honest. Because, if it "didn't", YOU folks would be the 2nd to know about it.

It works just as it is suppose to. It is a little stiff but could be just because it is new.

What can I say.  This works like it should.

it works good, but the way you set it is kinda difficult and the instructions are not the most clear on how to set it properly. But it does work as it is supposed to and seems to be right on the money when you set it up right.
