Wmkiyang Plastic Leak-Proof (3 Pcs)

the items were used on my five gallon water dispenser. I will buy it again if needed.

It is a good product

nice and easy to use, but little hesitant to use when bottle is full of water and carry it because of the fitment is not that tight as much. but it is use-full when you have a little dispenser

I like that the bottle tops fit nicely. Depending on the lifetime of the tops I'm hoping I can cut down on the amount of plastic I use. The ones I used before would crack and needed to be replaced often. My only issue is the circle in the middle doesn't stay well. I fixed by inserting a plastic one from my previous tops.

These lids do not work if you have to tilt or flip the 5 gallon bottle! While the diameter is the same, they cannot withstand the pressure and will pop off. I found out the hard way and had to clean up water everywhere!
