Caps came as described, quality is decent, fit was good (only one properly threaded, but thats fine as I need one of the holes in our 55gal water barrel to be easily accessed for pumping).Shipping time was also a day earlier than the estimate too, so that was nice.Good bang for your buck if you're looking for a quick solution to losing the original caps to your barrel.

They fit my barrel just right. A little tight at first but after a while in the sun, it has conformed to the barrel opening or the barrel opening conformed to the caps. Either way, they fit just right now.

Works great on both 30 and 50 gallon plastic barrels, and at a fair price. 5/5 stars. Will buy again.

I purchased these for a rain barrel and they worked perfectly. Leak proof seal!

Caps look made well and gaskets looked good.Unfortunately these were about 2mm-4mm too big for the barrels I have 😭Looked exactly the same except just that tad too big. I haven’t been able to find the exact size I need so far but if you have old barrels from 90’s it’s possible these caps may not work.
