Easy to use, great results
Easy to use, easy to clean! Everything snaps apart for thorough washing. I appreciate the real airlock created with the water in the canister, compared to the simple silicone valve style. So far I have made my own pineapple tepache, vinegar, saurkraut, and several kimchi variations. I even fermented the unripe tomatoes, onion tops, and broccoli leaves from my garden that would have gone to waste. These help me save money and eat healthy!

Worked great!
I’m new to fermenting pickles, but found that the water lock was the best at keeping out oxygen. These were easy to set up and use. My counter looked like a science experiment, but it was also fun to see the gasses make the float rise and fall as they released. I would buy it again.

Working OK
I used these for the first time two weeks ago with home grown beets & carrots in a brine. They seem sturdy butI need to fiddle with the air locks a bit as they seem wobbly at the silicone gaskets. No mold has developed, though, just the Kahm yeast and a "mother, right on cue." I also plan to use these regularly for small batch sauerkraut and in half gallon wide mouth canning jars rather than carboys for wine with some of this year's elderberries and grapes.

Genius! Convertible lids are the way to go.
These lids and water locks are just what the beginning fermenter needs! No need to watch, wait and burp your batches. This set-up takes care of it without intervention. I've been using them for several years and they are holding up well. I love the fact that I can take out the water lock and use the silicone plug to close the hole without changing lids. Someone was thinking!

Excellent Product!
So far, these have worked fantastic. This has opened up the ability for me to use all my jar sizes for fermentation! Excellent product.

Not bad, but not great
I bought these to start my new mead-making hobby as starter fermentation vessel tops. Ended up buying a 6 pack of half gallon mason jars to work with them. While the process did work, I find that the tops don't screw on to the mason jars so easily (I was able to get them to work with a seal, but it takes some oomph to get them on). The other thing I didn't like is that because the metal is so sharp, the rubber gaskets are very easy to rip. In my first batch of 2 jars, I ripped both of them and had to replace them. If you get this product, be careful how you put the rubber gaskets onto the lid.
