I've bought these twice, they are so useful
Using these in combination with Ball Jars has been the best solution for home fermenting I have found. Super simple and clean and effective.

Amazing product and seller!
I purchased the Fermetnology kit comprising 2 wide-mouthed Mason jar lids plus an air extracting pump as a present for my husband. The lids were extremely good and all seemed set for our first fermenting experience. However the pump didn't appear a tight enough fit to extract the air, so it appeared to be either dud pump or a design flaw. After contacting, seller who were a delight to deal with, a replacement pump arrived and works a treat! I found the seller to be totally committed to their product and customer satisfaction. I'm extremely impressed. I heartily recommend their product - and also think it's good value for money as it makes fermenting extremely easy. My hubby and I are 2 happy bunnies.

Works well
Good equipment. Would have been five stars but the pump doesn't work. I've made kimchi and sauerkraut. Both have been successful.

Works
Was very excited to get this to make sure my ferments don't have air anymore in them. Tried them on my new batch and it seems at least one of them lost pressure within a few minutes and others lost it overnight. Not sure they work very well and the silicone valves in them also seem to move a little too much making it unreliable. Edit: The seller was more than responsive to my issues with the kit I was sent. A replacement was promptly shipped and it seems to be better than the last batch (at least for the two days I have used it) in holding off the vacuum and not losing pressure. Would certainly recommend this not only because it works but also the sellers service and prompt response to my issues.

Upped my fermenting game!
So easy to use and peace of mind while my goodies are fermenting. Wasn’t sure if they would be worth the outlay but they certainly are as I’m in an old house and had spoilage using the burp method, no more spoilage using these🥳

Do not fit kilner jars properly
Uk buyers, these lids do NOT fit onto Kilner jars properly. They can’t screw on enough for the sealing ring to make contact with the jar. You can possibly get over this by finding a thicker sealing ring but I’ve not yet tried. Other wise the product seems very good, may be worth sourcing mason jars to use with it.

Nifty piece of kit
These are great. The lids screw on hand tight, the air is pumped out and a negative pressure is maintained by the seal in the lid until CO2 replaces the partial vacuum. Brilliant. Buy once with the pump and any other purchases can be just the lids which are around a fiver cheaper.

Not Glass
I purchased these as the as it states they are made from Glass...These are Not Glass! just plastic, and the box tells a different content, it has 4 lids and a pump, the box says 2 lids, 2 stones and a pump? Haven't used them so no stars, although I had to give 1 to get past this page.

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.

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!!!

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.

Kapakların çapı ülkemizdeki standart kavanozların ağzına uygun değil. Kimisne küçük kimine büyük geliyor

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
