These lids are so cool! I am experienced at fermenting and have used the airlock lids with the little plastic thing on top that you fill with water. This is a much better design in my opinion! Things I love about them

I absolutely love these lids! I use them for pickling and they are great After losing 4 of the center rubber pieces when washing them (don’t ask), I sent the company an email asking how I could purchase more. They replied within one hour (in the middle of the night) asking me how many I needed and what address to send them to. That is great customer service!

I bought another kind of glass weights first (they cost less), but longish handle going all the way across the weight is not tall enough and sometimes slides out my hands when wet, so I ordered these next. Knob handles work much better

Tried them all…many glass weights out there, some better, some worse…I love these the best and here is why…* the nob on top actually works…you can grab it and lift the weight from your ferment…* the weights are solid glass full thickness…no well or indentation on top to collect the liquid…* heavy enough to keep everything submerged…
