Excellent product!!! Fermentation game on!!!
These fermentation lids are literally awesome!!! Screw onto wide mouth lids with ease and are made of quality plastic, they are extremely durable and well made. Was unsurr about the pump but after watching my saurkraut, i see how incredibly useful the pump is to remove the excess gas by removing it. I can forsee they shall last a long time thru many many batches of fermentations. I Def recommend these to anyone looking for a quality product that surpassed my expectations. Thank you for an excellent product. Will most def purchase more. Haven't found any that I can just purchase without the pump....Def don't need an excess of pumps with every 4 lids bought. Just a thought!!!

Works Great and Fantastic Support
I ordered a full kit and one of the glass weights had a problem. I emailed Fermentology and quickly got a response. They very quickly replaced the Kit, although I was just expecting the weight to be replaced, they replaced the whole thing. Then the use. While I was waiting for the weight. I tried out the rest and did two batches of Sauerkraut. One with the Mason tops Pickle pipe and one with Fermentology lid with pump. The one with the Mason tops Pickle pipe, I had to throw out due to mold. The Fermentology lid were it was pumped, once about every two days (from the CO2 build up), came out without a problem and a PH of 3.8.. The Pickle lid Never dropped below 4.5 PH.. I'm very happy with the Style of weight, lid and pump of the Fermentology's kit.

Easy to use and works super!
These are simple to use and work great! The reason for only 4 stars is that one of them does not work when using the pump to get the air out! But that said Excellent product! Been fermenting for years and really am enjoying the "easy"!!

Perfect set for new fermenters
This is a perfect collection of pieces in order to make fermented pickles. Easy to use. The glass weights are smooth without imperfections and they fit perfectly in a wide mouth jar to keep your produce under the brine. I'd never fermented before but with this kit I felt confident. I knew there was an air lock protecting my food from air in the room. Since I've never fermented before that made me nervous. The pump was a fun little activity. Each night I'd pump it a little and watch all the bubbles rise to the top. I liked it so much my Sister-in-law now has this kit. We went to a farm, picked out our own head of cabbage and now we are making sauerkraut for our hubby's. I may even give kombucha a try next😁

Not sure the pump actually does anything
This is a great concept... having a pump to remove trapped air but I'm not sure it actually does anything. The videos I've watched say to use the pump until you feel resistance. I don't feel any resistance and don't really see anything happening either. The lids seem to be a good quality and let gas out and the weights do a good job of keeping food submerged. Maybe I have a faulty pump. Who knows. **Update** The company reached out to me about the pump. They sent a replacement and I've just used it. Waaay better! Definitely had a suction this time and removed air from the jar. This is a very easy system to use and very happy with the customer service!

Good product, terrible customer service
Good product, terrible customer service. This is a sad review as the product is actually really good, but one of the rubber air lock pieces had a manufacturing defect and wouldn’t seal. I was told the only resolution was to initiate a return with Amazon, which is not a viable option since the 3 other kids are being used for a 30 day hot sauce ferment. If a company isn’t willing to send a replacement piece that they easily could send they won’t be getting any more of my money and shouldn’t get any of anyone else’s.

Best fermenting setup that I've ever purchased
I have many fermenting vessels and tools but this one is fool-proof, use these along with the Simply Sauer glass weights and you can't go wrong. I pull a slight vacuum at the beginning to remove oxygen, then when the ferment activity is done I use the vacuum again to keep out the nasties. It's perfect for removing some cabbage etc. for a taste and then pulling a vacuum which will remove the oxygen since there is no longer Co2 production to push the oxygen out again. Will definitely buy some more of these and the glass weights. I also like the ability to see through the top, which gives these a great advantage over similar vacuum tops.

Excellent Setup for Lacto-fermented Peppers
I've been using these since 2018 to ferment peppers and they're fantastic. The plastic holds up well to use (I don't use a dishwasher as the heat could deteriorate the plastic and rubber valve.) and I've only cracked one handle by over-tightening by accident. Unlike some other foods, peppers ferment better (and more safely) in an oxygen-less environment and this kit does the trick. I use mason jars along with the lids which allow me to ferment a lot or a little depending on jar size (wide mouth). The pump is sturdy enough and does the trick of really getting the air out, but not much force is needed either. I've debated and weighed other options, but I keep coming back to these. Can't go wrong.

Using these in combination with Ball Jars has been the best solution for home fermenting I have found. Super simple and clean and effective.

Das perfekte Set, die Deckel passen genau auf die Mason Jar Wide Mouth, die kleine Pumpe arbeitet leicht und schnell, falls es mal nicht sofort klappt, hilft es, die kleinen blauen Ventile einmal aus dem Deckel zu entfernen und unter Wasser gründlich zu reinigen. Auch zum Transport von Smoothies unter Vakuum super geeignet, beim Fermentieren verschwindet das Vakuum nach einiger Zeit durch die entstehenden Gase, es läßt sich aber leicht nach der Kontrolle des Inhaltes auf Geschmack und Konsistenz wieder herstellen. Ich hab schon ein zweites Set gekauft, diesmal nur vier Deckel und Pumpe, da ich Gewichte mit Griffmulden noch besser finde.

Después de algo mas de un mes de experiencia, el producto me funciona, y con el se obtienen unos fermentados muy sabrosos sin mohos. El único problema del producto que he comprobado que tiene, es la falta de controles de calidad en funcionamiento de la bomba seccionadora y de las válvulas de las tapas. En uno de los pedidos que realice, la bomba succionadora no me funcionaba. Por lo que tuve que devolver el kit. En otro pedido, la válvula de una tapa venia defectuosa y con ella era imposible vaciar de aire los botes. He leído comentarios de compradores que dicen que el producto no les ha funcionado, y seguramente es por que algunos de los componentes del kit que adquirieron venían defectuosos, y no se dieron cuenta de esto porque no lo comprobaron antes de iniciar el cultivo. No soy de poner comentarios a los productos que compro por amazon, pero dado lo importante que es para la salud de los demás el realizar un buen fermentado, quiero recomendar a todo el que compre el kit, que compruebe tapa a tapa si se crea el vacio, probándolo en primer lugar con el bote completamente vacio. Cuando se succiona el aire del bote, el movimiento del accionador de la bomba se tiene que hacer cada vez duro, hasta que cueste mucho. En ese momento, en el interior del bote se habrá creado el vacio. Y cuando se abra el bote, se ha de escuchar el tipico silvido de que ha entrado de nuevo el aire en el. Si esto no se consigue tal y como he descrito, hay que devolver el producto por defectuoso y volverlo a pedir.

If you are looking to get into fermentation- i truly recommend this product- I’ve been fermenting for many years - took fermentation at culinary school - this is fool proof- I won’t go back to the old school methods- these are great great
