Review on Thermometer Brewing Fermenting Temperature Adhesive by Roberta Gonia

I bought these to keep Kombucha cooking in mind. The only problem I see is that the colors aren't as vivid as the photos, so it's a bit difficult to tell what the actual temperature is. The thermometer sticks come in a plain white box with no instructions, so you'll need to return to the Revain page for instructions. They work as advertised, just wasn't sure how to read the temp, but I think I have them now. You could probably use more than one of them, but it's good to have a spare in case one of them stops working.
