Home Fermentation Kit With 4 Wide Mouth Fermenting Lids With Airlocks, Oxygen Extraction Pump, Ideal For Sauerkraut, Kimchi, Pickles & Fermented Vegetable

This product is absolutely amazing! It was my first time fermenting, and I was concerned about safety, mold, and harmful bacteria. However, if you follow the instructions, there is nothing to worry about. The oxygen-removing feature is a game changer. It made the entire fermentation process simple and worry-free. I just opened my first jar after 14 days, and the sauerkraut turned out amazing. I highly recommend this product to anyone who is new to fermenting or wants a safer, easier way to get great results.

These are fabulous no mold no normal fermentation karma yeast even. Checked ph at the end, perfect. No burping and no sputz on the tops. They are well worth the money. Using the pump to illuminate most of the air takes all the concerns out of the picture. Definitely fits my wide mouth Ball jars, pints and quarts.

These lids are perfect! Makes fermenting a breeze. Fill your jars and pump all the air out. No burping, it burbs itself.

This was my second set of airlock lids purchased. They eventually worked well after resetting the one way air valve on 3 of the 4 lids. Also silicone/rubber jar rings kept falling out when placing the lids on the jars on 1st time use. Stayed in place after checking acidity and on second batch. They performed well after initial problems. Lid calendar work well.

These lids work great for fermenting. Easy to use and convenient with month/date markers.

These are fine, but the one-piece setup means that as soon as the pump breaks down, and as cheaply as it's made it's going to break, then your fermenter lids are virtually useless. Yes, you don't need to vacuum to ferment, but it's much safer, especially if you want to use a 2% brine. At least with 2-piece lids, you can use a wide mouth mason jar adapter to create a vacuum. The main issue is that when the vacuum pump breaks, there's no way to get a replacement, you have to buy the whole kit again (I know, I asked). The lids seem sturdy and well made, but that pump is flimsy and cheap with zero consideration for the user.

Do not pump after initial jarring. These worked excellent and surpassed the burp method and the silicon nipple lids. Easy to clean, use, and reuse!

I like this product so much! I wish I would have had this years ago! This makes fermenting worry free! No burping jar lids. Just put your ferment in the jar, set the date on the lid and forget about it! Fast shipping. I am thinking about ordering another set of lids! I always need to have more! Great product!

Tras abrir la caja, descubrí que la bomba no extrae el aire de los frascos Mason. La bomba no aspira aire. La junta interna no ajusta firmemente contra las paredes del tubo; existe un espacio visible entre ambas. Considero que este producto ha sido fabricado con un control de calidad deficiente o inexistente.

Very good but give it a 4 because it's very expensive here on Amazon in Sweden.

These work flawlessly. Very happy with my purchase. No I can do long ferments and not worry about any nasty mold

Works well and keeps contents from molding so far very happy.

These are great. A must have if you like to ferment veggies.
