they are ok

Good for the purpose

These fit San Bernando glass sparkling water bottles, used the bottles to create compote. When original caps get lost, these fit the bottles, the only issue is they are not as tall as S. Bernando caps so the grab surface is a bit narrow, but with some tinkering it's easy to make them more grippy, just smeared some goop (rubber glue) around the cap, cut a thin piece of old rubber tube and fix it around the cap.

I like to make syrups. These work perfectly to re-use all the syrup bottles.

They fit, they work.

Great caps lets me reuse brown bottles bought at the store and not have to buy new bottles

Like another commenter here, I feel bad knocking these down in the review but the description is wrong and I wasted my money. They are good quality lids and I'm sure they would be great if you had bottles that fit them but they do NOT fit standard screw-top wine bottles. The diameter is right but the screw threads don't even come close. So what do they fit? They do fit a standard soda bottle. They do fit a syrup bottle in the cupboard. They do fit the isopropyl alcohol bottle in the medicine cabinet. They don't fit the short-thread tops of many water bottles. I'm not sure how the size (including threading) is supposed to be described but if you're looking for wine bottle caps, keep looking. Update: The description from the manufacturer is correct (28-400 thread), I just didn't know how to interpret that. The bad data was in one of the responses to the questions. Bumping my rating back up because it wasn't the vendor's fault.
