Great System
This is a very good system for fermenting small batches imo, especially if one is into canning too, because jars become multi-purpose. I have five on the go currently, and I will be adding today's picked gherkins, and would have more fermenting if it wasn't for one major issue - Amazon Prime are now using Evri and our last few orders of this product have disappeared/been returned. Anyway, rant over. The lids are solid and easy to clean and beat any other small-batch system that I have used by a country mile. For large batches I use traditional crocks, but wouldn't hesitate to use these if I had suitable >2litre jars. Their glass weights are good too.

Nice Bit of Equipment
So much better than the silicone nipple style ones you can get on the cheap on Amazon. I'd much prefer the glass varieties but as a test run I got these and they haven't disappointed. Construct them, prepare your ferment, stick these in then forget about it for 6 weeks!

Not compatible with Kilner jars
Nothing to tell you in the description if they’re suitable with the most generic mason jar on the market.

Non è ermetico
I tappi in dotazione sigillano male..fidatevi ho provato una decina di barattoli e una volta avvitati vengono via solo tirando senza svitare..

High quality, easy to use, with sturdy lids
Very high quality and easy to use. The lids are actually made by Masontops.

Simple, efficient, easy to use
I love this system. It's easy to use and clean. Also, mason jars are easy and cheap to replace. It's more versatile than a big crock jar and allows for smaller batches if you want to experiment. A crock jar, like the one I accidentally broke while washing it, cost me 80+$! Another benefit of this system is that you don't have to monitor the water seal (well, not for the length of time I lacto ferment, 2-4 weeks).
