Review on WINBOB 5PCS Non-Spill Caps: 55mm Snap On Replacement Water Bottle Caps - Anti Splash Peel (3 and 5 Gallon) - 5 Piece Set by Anthony Hicks

Why I bought it: Every time I refilled my water bottles I had to tape the tops of the old caps with tape to keep water from spilling onto my car seats. What they are good at: They seal really tight and keep water out; They are doing great work on that. Also: when I install it on my dispenser, they don't spill because of the internal spray cap. Problem: These are not reusable lids. 1) Once the outer (blue) cap is snapped onto the bottle, there is no way to remove it. This is probably because after forcibly opening the water dispenser's inner overflow lid, it is not possible to close it again for reuse. What I did as a workaround: use a large flathead screwdriver to poke in the hole and pry off the top. This works great for one or two, but then the lid gives way and breaks. Using a smaller screwdriver will instantly destroy the cover structure. To be fair to the manufacturer they are not advertised as reusable so keep that in mind. I assumed they should be, so it was a mistake on my part. Bottom line: if you're happy with buying them for one-time use, then it's worth it. Good quality and doesn't leak. If you need a reusable bottle cap, this cap is NOT for you.
