Came packaged well and easy to put together. The caps are a little hard to get off, but other than that I think had less growth of anything else on top of the brine than when using a coffee filter. The lid seals are great and just don't fill jar so high that you can't get the stem of the airlock to seal into the o-ring in the center.You can use the lid center o-ring cap to seal it and put in fridge if want. But I just use my regular mason jar lids. Liked them enough to buy a 2nd set.

This worked. I made sauerkraut in jars and it turned out great!

Simple, reliable design makes managing ferments quite easy. The silicone fittings are very good. Recommended.

Purchased an earlier version of this product from this manufacturer and was pleased with sealing process but realized that I had to be careful with the spout to prevent it from being damaged. The newer version reduces the likelihood of damage during sealing.

I guess you get what you pay for. One of the air locks body cracked the first time I used it. I have been extra careful since, and the other three are alright upon the second use..

Do a good job keeping air out, but hard to clean. Don't try to boil to sterilize - they will melt - ask me how I know.

These are just the job for home fermentation.Regarding the jars that they fit: I have Ball brand wide mouth jars and they fit perfectly. Indeed, the seller's description states that they fit Ball jars. They also advise that they are for 86mm (8.6cm) wide outer diameter mouth. So I suggest that people check the measurement of their jars before ordering. I found that the thread on one was a little rough the first time I put it on a jar, but afterwards it went on smoothly.

non economico, non molto pratico, funziona abbastanza bene

Simple to use and clean. These lids will fit the Kmart Australia 1 litre preserving jars that cost 3 for $6. That's a lot cheaper than the imported American ones. Once the fermentation period is over I just replace the lid that came with the Kmart jar and place it in the fridge/
