This is an air- pump that is made to sit (screws on actually) on an 'office cooler' style water container. This is stupid simple to use. Push down, air goes into bottle, water comes out spout. Box comes with several feed tubes to use pump with 3, 4 or 5 gallon bottles. My wife uses this at work - bottle sits on floor, push pump- get water. Since we are in a seismic Zone of 5, the bottle stays on the floor. The one at home is used with our backup water. We chose to store water in 3 and 5 gallon jugs with handle. This setup - when needed - sits on the kitchen floor. After 3 years of nearly daily use, the one at my DW office is still working just fine. I've never had an issue with the one at home - even with infrequent use. Price - @ WallyWorld is $11.42. A clever bit of kit that just works and keeps working as it is supposed to -- all at an excellent price point. I do not recommend using the handle to move anything but the empty (or almost empty) jug. I'm not sure how well the screw-on cap would work with lifting a 40# bottle... (Shrug) So I don't do that. We used to use (and still have) one the Alliance 5 gallon square water totes. And those work - but tote will have to sit on the counter to be used. I'd rather have the counter space. YMMV. (Not for contest. I was looking at my posts for the last year and thought it was well-past time for me to contribute something worthwhile for board members/ visitors) .
