Review on Convenient Dr. Woods Soap Bottle Pumps - Perfect Fit for All 32 oz Bottles: Dr. Woods and Dr. Bronners (Pack of 2) by Rachel Johnson

Very good. It has a very long hose so you can empty the bottle completely. Just note that you will feel a slight resistance when inserting it into the bottle. (32 ounce bottle) It also has a cool locking feature, although I'm not sure why you would need it. Maybe if you've moved and wanted to make sure there wasn't an accidental leak. It can also act as an effective deterrent to marauding bullies, but in any case be aware that it's in the locked position and you'll need to push down and turn left to unlock. It's embarrassing to say how much time I've spent trying to figure this out. Finally I went to their website to get an answer.
