3 Pack Kombucha Fermentation Adhesive Strip Thermometer - Displays Temperature in Degrees in Celsius and Fahrenheit - Easy to Use - Accurate - Great for Kombucha, Beer, Wine, Vegetable Fermentation

I have three gallons of kombucha going at all times in my kitchen and need these temperature gages to make sure they brew at the right temp. It may be a little hard to see but I just use the flashlight on my phone and then it’s easy. They’re actuate and stick to the glass container well. I hand wash them after each batch and they haven’t come off or even lifted yet. I bought more just in case but haven’t had to use them.

Great value for the money, easy to use, adhesive is fine. Can be difficult to read like others mentioned, but shining a light or having appropriate lighting makes it no problem.

I have this on the outside of a large glass container where I brew kombucha so its important for me to know the temperature. I've washed the container a few times and it doesn't appear to be peeling off at all. The temperature change causes the number on the thermometer to have a little box around it that can be a little hard to see in dim light but it is pretty easy to recognize which temp is highlighted.

This strip does not show temperature. I have tried two and both have been bad.

Received these yesterday and immediately stuck one to the side of my kombucha jar, it stuck really really good, I wanted to adjust it down a tad and it ripped when trying to adjust it. In a moment of panic I pushed it back onto my glass container. It stuck again and has been showing varying degrees so I know it is working. I haven't washed it yet to see how it does as being reusable and will update once I know a little more about the product usefulness. So far it's working as described, and like I said, it sticks very well!!!!

I use these for my kombucha, jun, water kefir, and ginger beer plant ferments to ensure my mix has cooled enough before I add the ferment cultures to my batch. They work exactly as they should. If I have any problems with durability I will update my review but they seem well made and comparable in quality to the one I purchased specifically from a fermentation company. Thank you!

I use these stick on thermometers in my Kombucha brewing. I find the reading is accurate but very hard to see. I was familiar with this style of thermometer as one came with my brewing kit and that one was much easier to read. Unfortunately a family member broke my kombucha bottle and threw it out without removing the thermometer. Bottom line, the temperature accuracy is there and the price was good for three of them in the temp range that I wanted. If you don't mind having to really look to see the temp then get them, just don't expect it to jump out to you.

These are great, accurate and stick well to glass jars that are smooth.

Great product. Easy to use and works great. Love these stripes. They stick onto my glass jars properly and display the temperature of the contents of my jars. Will buy from this company again.

does what they're supposed to do

We use the strips to make sure the tea for kombucha is the correct temperature before adding the scoby. It is accurate but not very easy to see the square that indicates current temperature. Very faint. Need good light coming at the correct angle. Probably won't order again; will just use a thermometer.

Accurate and sticks well even during washing

I must have a duff batch because none of the ones I received show the temperature…there is no difference at all.
