As advertised they do not drip as the first ones I purchased. I am very happy with this item.

Bought this for sanitizer gallon bottles. Pump action is good, used some plastic collars to limit the downward travel as it is very high. Works for what I need it to do but wished it had the capability to lock when fully compressed. Other issue is that the pick up tube is about an inch short of the bottom so there will be a large amount of product remaining.

If you do production detailing, little things like this add up to efficiency and savings. I use this pump for viscous materials. Like leather conditioners and soap. Trying to pour direct into a bottle you'll find is a waste of material and not consistent measuring. Same applies to a funnel. It's slower, no accurate and you'll have to clean the funnel. I just pump into the sprayers, drops right down and I'll dilute it with water after.

Works great. A must have

Well, yes and no. I would buy this pump again for soaps, and simple chemicals.

I put one in some Meguiars D140 Wheel brightener and in less than a month it had corroded the vacuum mechanism to the point of unusability.

Now, this problem could obviously be remedied by removing the pump after each use, but who the hell is going to do that, am i right? I guess i'll need to go to US Plastics and get a chemical resistant pump or just a spout to put on the gallon to distribute the chemical.

These work really well! I've used them on Meguiar's and 3D gallon jugs and have not had any issues with any dripping. They are rather tall, but that's not an issue in my opinion. I've used these for measuring out D116 and 3D Pink Car Soap. These make it significantly easier to measure and fill foam cannons, especially since pouring often results in soap all over the exterior of the bottle (due to small openings).

Works great, consistently measures out 1 oz of product to top off daily use bottles or to mix/dilute. I have several and will buy more as needed.

PROS: For the price - nice quality pump... saw the reviews that this pump will not drip like other offerings out there; that is in fact the case! CONS: But I will not purchase again because the pump is VERY high (especially when added to an already large 1gal bulk supply) and doesn't fit on any shelf in my floor cabinet (it's probably 22" when added to a Mr.Pink bulk). The pump does not fully compress and lock in a lower positions so it's constantly fully rebounded. I literally have no where to store creating another problem I have to sort.

Doesn't drip and consistently delivers 1oz of product per pump. Works great!

Does not drip. Great product, I bought a few other ones from different companies before I found Detailed Image and they all dripped.... So I was skeptical about this one from DI but let me tell you this No Drips, No Wasted Product.... Perfect

Does not drip!
The reviews for the Chemical Guys pump say it drips after you use it so, I bought this one instead. Works just fine, no drips.

I bought this item to go along with my 1 gallon chemical guys citrus wash soap, and I am very satisfied with this product it performance exceptionally, one full pump gives 1 ounce of solution, also it fits perfectly the one gallon bottle.

Works as advertised. Makes the transfer of chemicals from container to container more convienent. I buy one to go along with every gallon of cleaner that I purchace.

Could not live without it... I use it to transfer products from my 1 gallon containers into my Meguiar's 32oz Spray Bottles so that I can properly dilute them without making a mess. I also use these dispensers on all of my 1 gallon shampoo jugs and pump the shampoo directly into my wash bucket. Makes things much quicker and easier!

Does exactly what it should.
