They've been on my list for a couple years. They are just so simple. What brand are you trying?

Yeah, I use them. especially when i have alot of ferments going and dont watch. bought off amazon, no name brand.

bought off the bay, no name brand.

You made me look at ebay where I saw them for as little as $6.95 for five of them, though I did not look at what shipping would be. I had been thinking to pick them up at Target where they were $21 for four of five of them (not sure)-- Pickle Pipe brand, I think.
