1 Gallon Pump Dispenser - Leak-Proof Pump for Gallon Jug with 1.5" 38/400mm Neck, Lock-Ring and Standard Cap Closure - Durable, Reusable, Great for Any Foam Soap Dispenser, Cleaner, Detergent

I ordered this product and it arrived promptly (as soon as I had aggregate orders over $25 under Amazon's add-on program for inexpensive items). The pump seems as if it were specifically made for the Biotone gallon Advanced Therapy Massage Lotion that I use. The intake hose and the spout are just the right length, and the lotion came out after only a few initial pumps to prime the line. I've only used it to fill up a smaller Biotone container one time, and so I can't comment on how long this pump will last--hopefully indefinitely.The remainder of my comments do not specifically apply to this pump or even to this specific lotion, but to any thick lotion and any gallon jug. I first bought the gallon jug (without pump) and tried unsuccessfully to pour it into the 8 ounce dispensing container that I use (which happens to be the Biotone 8 ounce container of the same lotion). It didn't work--too thick, air bubbles, lotion oozing out and down the neck and sides of the small container, etc. (herein called a "Mess"). So I tried a funnel. Still a Mess. So I put the gallon jug in a tub of very hot water and hoped the lotion would thin out over the next 30-60 minutes or so from the heat. Nope. Still a Mess. So I looked up pumps on Amazon. I found several types where customers complained that the intake hose was too short, or too small in diameter for a thick lotion, or whatever. So I ordered the Biotone pump. It works fine, but it still takes practice to avoid some tendency towards a Mess.Even though the pump works fine, you still have thick, goopy, lotion going into a small bottle neck. If you don't keep the spout well down into the small bottle (or maybe no matter what you do), lotion will create an air bubble while filling and start to overflow even though the small bottle is not full. It's still a goopy process. But I think I see how to do it neatly. It's not the fault of the pump, and it will just take a little practice on what works for you.

I bought this to replace a pump that came with a gallon sunscreen container. Our original one cracked when the jug fell on the floor. This one seems sturdier than the original.

Good quality pump. Straw was longer than it had to be and was easily trimmed to length needed. Fit gallon jug as described. Dispenses well consistently. I am using on gallon of aquarium water conditioner.

Says it’s for a gallon sized bottle. Was too long but cut well to fit the bottle. The lid does not fit on the Cholula gallon bottle. Pumps well.

I have purchased this item in the past. Works well, never disappointed.

Not much to say except it’s a gallon size pump on the mediocre side of quality. I bought and am currently using it for my pureology gallon size conditioner. Have pushed that lil pump MANY times!! I pump the conditioner from the gallon into normal size container for the shower. So yeah LOTS of pumps!! Haha! It’s still going strong though!! Hope this helps!!

works well with the gallon jug of shampoo

I guess you get what you pay for. It fits a gallon jug, and it usually pumps (usually), but the pumping mechanism is separate from the fixed part... as in it is free-floating, and it can fall out. The liquid in the container can spill out. Overall, this is not a "good" product, only a "functional" one... and even that rating is marginal. If I were to buy another pump (and I will have to soon, I'm sure), I would not even consider these. I do not recommend that anyone waste their money on these pumps.
