2 Pack 1 Gallon Large Fermentation Jars with 3 Airlocks and 2 SCREW Lids(100% Airtight Heavy Duty Lid w Silicone) - Wide Mouth Glass Jars w Scale Mark - Pickle Jars for Sauerkraut, Sourdough Starter

I am very impressed for the price.Set was shipped in thick foam top and bottom with thinner foam wrapping in the middle, but enough air between the box and the glass to be pretty safe.My kit included:2 wide mouth fermenter bottles2 heavy duty lids4 silicone lid gaskets4 silicone airlock grommets with tethered stoppers3 three-piece airlocks2 cute wooden "chalk" boards with twine1 white marker (erasable? Haven't tried it)Bottles are think glass with a punt bottom, so lees will be deeper around the outside and more shallow in the middle. The liquid scale on the bottle is only useful for less than a gallon, but may be useful occasionally. Not sure about accuracy, though.The lids are very sturdy and seal tight with the gaskets. They will not buckle from pressure, and should not crack easily as they are have enough flex to withstand some abuse.The airlocks are standard, large size three piece locks, for 8mm stopper/lid holes.I have bought high end Italian glass carboys from brew supply stores that came with nothing except a flimsy box. This set of 2 complete fermenters with extra parts cost about the same as a single 1 gallon Italian carboy that I have. And, the quality seems pretty equal.The only thing that could end up bringing down my rating would be if replacement gaskets and grommets cannot be found. Time will tell if they retain any aromas/flavours that could potentially affect subsequent ferments. The grommets could probably be replaced with standard bucket grommets, but the lid gaskets could be difficult to find alternatives for.Other than that, these 1 gal fermenters are perfect for small batches, or for racking larger batches down to 1 gallon secondaries.

Well packaged, in properly cut foam, didn't realize it came with the little twine and black plaques with a paint marker which is super nice

I have purchased this set twice now because they work so well. I have been brewing my own kombucha in these for a year now, and they are like new. These are high-quality, thick, durable glass and handle a gallon of liquid. I have a batch brewing in primary in one jar, and another in secondary fermentation in the other jar. The airlocks are slick; I'm watching it bubble as I type. They clean up so easily, too. The only knock against the set would be the chalkboards; while cute and handy, the actual chalkboard part doesn't release writing easily so there are a lot of ghosted images. But really, you can pick up one of those anywhere, and it had no factor in my choosing this set. When I decided to brew at a higher capacity, it was a no-brainer to select this economical workhorse again.

Great product! Been fermenting mead for about 6 days now with no issues.

These are the perfect size for fermenting chicken feed for my 8 ladies. I am able to keep a good rotation going. They are easy to use and I love the chalkboard signs that I can write the date started the ferment. They are a nice touch. The packaging exceeded my expectations so that everything arrived safely and in good condition. They are sturdy and I think they will last a long time.

Great! Comes with all the equipment sans the goodies!

works exactly as one would expect. Its nice that it comes with spare parts.

Great product. Appears to function as described.
