the good thing is that they keep the water in the 5 gallon jugs, they have a small pop-off lid that covers the pop-open inside lid. they are durable but soooo difficult to remove! i have to use the handle of a metal spoon or butter knife to remove and i feel like I'm going to break it every time i take them off. It's hard! I have a water dispenser that i place on top of them and they fit snug on it.

Cant reuse them like I thought, once its on, its on. Great fit if you need a cap like is originally on bottles, but not for reusable.

You don’t need four. I’ve reused the same cap like three times so far. Just make sure to sanitize it and pop the seal back in before putting your water jug back.

These caps were so difficult to use. Once put on my 5 gallon jug the cap half was almost impossible to take off. I took a pair of scissors and pliers to two just to remove them.

So I was kind of curious about getting these caps because I had eight water bottles from a delivery service that would just not come pick them up so I now go to Walmart to refill my 5-gallon water jugs which I can do for $1.95 instead of the $7 per 5-gallon jug that I was paying using the delivery service plus their delivery fee so these reusable caps have basically made it where I get more than $5 off per refill on a 5-gallon jug plus I can reuse them and they work perfectly to keep the water…

As others have stated prior to me, READ REVIEWS before purchasing. Great product, tight seal but they’re not reusable. Ridiculously tough to take off. You’ll have to determine your preference.

Works as advertised. When removing, just remember to run under hot water for about 30 seconds. Makes removal much easier.

Not heavy duty, but works. Will bend on the edges a little, but will not come off when installing water jug on your cooler.

If you're trying to refill 5 gallon jugs of water and then cap off your refills, don't get these. In fact I'm not sure why you'd want these unless you're trying to seal your jugs with something that you can't easily remove.If you use a Primo water system, just buy the white lids from the manufacturer.

omg you are supposed to live this cap forever on the bottle or what. I almost broke my fingers trying to take out this cap to refill my water bottle. Literally i cut the cap to take out

I wasn't expecting much but they worked really well. There were spelling errors on the packaging which made me lose confidence but it works well.

Fits perfectly but it is almost impossible to remove. I soaked it in hot water and was able to remove it once but after that, not possible.

They work but I wish there was an easier way to reuse them. Hard to remove for refill, but once back on, they do the job They may not be eco-friendly.
