(Pack of 5) Fermenter Adhesive Crystal Strip Thermometer 46-82F (8-28C) Ideal for Kombucha, Beer, Wine, Brewing and Fermentation …

ok

Works great for monitoring my kombucha. I had never used one of these before and unfortunately this didn't have instructions on what to expect (maybe add a little paper in the bag with the strip or a label on the bag?). If there are two colors that show up you tske the average of the two numbers as the accurate reading. Also, give this a chance to work. I contacted the seller since I was seeing nothing on the strip....it stayed white for hours. The seller Brew Box Kits got back to me VERY quickly, probably within minutes of sending them a message, and he explained how the strip worked snd even attached a photo of how it should look for reference. Very helpful in troubleshooting. I left it overnight and voila, in morning, it was bright and visible! So maybe don't get discouraged if it doesn't read right away.

Works well, but I purchased it for brewing kombucha and the ideal brew temperature is 75 to 85 ° and this thermometer only hors up to 83°. So NOT GOOD FOR KOMBUCHA. But fine for other things.

These stick-on thermometers are effective for keeping tabs on the temp of your fermenting beers in glass carboys. I would give these 5 stars if they were easier to read, but I have to use a flashlight to see the readings even in normal light. So, they do what they advertise, and the instructions does warn you might need a flashlight to read it, but I was assuming they meant in darkened conditions, not in every condition.

Good product, especially for the price. This works just as good as the beer/brewing thermometers. These are only water resistant as described. I used one recently in a water bath as a way to keep the temp down and the thermometer got ruined. Nothing against the product since it doesn't say waterproof, just a warning that the resistant is noted for both functionality and maybe adhesive quality.

Worked very well with my mead making

I used these to measure my Kombucha temp as it brews. I have a very cool kitchen, even in the summer so It's hard to keep it up to temp. Between a seed heater pad and these, I can make sure my kombucha is at the correct temp for brewing.

Hard to read unless you get very close to read thermometer
