Samshow Fermentation Kit - Includes 4 NonSlip Grip Glass Fermentation Weights and 4 304 Stainless Steel Fermenting Lids with Airlocks for Wide Mouth Mason Jars Ferments Such As kimchi, Sauerkraut, etc

This is my first time trying lacto-fermentation. As other folks helpfully noted, you fill the plastic topper halfway with water. I placed brine-filled jars of veggies in my pantry for about 5 days (in a pan to be safe but nothing leaked). Although two of my toppers arrived cracked they were still useable (not leaking water). The company is very responsive and will make it right if there is a packaging issue (partial refund or replacement parts if available - the glass weights are very heavy, and things bounce around during shipping even with bubble wrap). Quick tip: it's easier to grip the glass weights and pull them out of the jar if your hands are completely dry. For my first try at this, I'm pretty satisfied with the results and have more lacto-fermentation plans - thinking about purchasing more!

These are for wide mouth jars and fit well but they are hard to get out when wet

I'm just getting started doing fermented sauce, and even though I have many of the parts from brewing, it's nice to have a dedicated set for peppers.Very complete, just add jars.

These are great ! Easy to use and I got exactly what was shown.

It's really unclear from the instructions that were not in the package, but scattered on the site with a lot of unhelpful pictures. what is the airlock for? One paragraph, after sifting through the web page says something about putting water in it, but the other paragraph does not. So do II put water in it or not? Some simple instructions in the package for those of us who are not fermenting gurus would have been nice. I also have no idea if I should take the cap off the airlock or not. I'm assuming leave it off. Very, very unclear non-instructions.
