Review on Non-Spill Replacement Caps: Magicfour Water Bottle Caps For 3 & 5 Gallon Water Jugs by Alejandro Wolf

I really wish I'd read the reviews before I bought these. Once they are put on the bottles they do not come off again! I got them because I also bought a stand to hold my water jugs and wanted to be able to have the bottles sealed tight as they lay on the side on the stand. So when I refilled the 5 gallon jugs I had to fill them through the little hole in the middle but since the tiny cap that actually seals the lid is on the inside, I couldn't seal them properly. So when I placed them on the stand the water started spilling out. So I spent another 30-40 minutes fighting with the kids trying to get them off before I gave up. Definitely would NOT buy again.
