Brewing Thermometer Strip Adhesive Strip Thermometer Aquarium Thermometer Strip, Temperature Test Strip Thermometer Sticker for Fish Tank/Kombucha/Fermentation Jar 39 to 97℉/4 to 36℃ (10pcs)

Order these strips specifically for my wine cooler fridge. I just didn't trust the gauge on it. I used a kitchen meat thermometer to stabilize the cooler at 55°F. Used a scotch tape to attach strips to the bottom, middle,and top of a glass door. As you can see, the readings are pretty accurate. I'd say to 1°F. However, the lower the reading, the harder it is to see. If you can't seem to see what part of the scale is activated, shine a flash light on it at an angle. Don't forget to remove a clear protective film on the front side. It makes it a lot easier to read the temperature!

Works very well

Nice for the price

They work great especially on my kombacha container to make sure kept in right temp which Is hard to do in the summer. Only con is hard to read unless right up close to it

Works well! Sticks great to 1 gal carboy, temps seem accurate.

The strips would give a temp reading, but very hard to see and determine. I had to pick up my glass gallon bottle full of brewed tea and move it in different directions to read the temp when getting ready to brew kombucha. I probably won't buy that brand again. I'll order from the company I bought my kombucha kit from next time.

these appear to work as intended

READ THIS BEFORE YOU PURCHASE-- This is 1 of the worst PET products sold on Amazon. They not only didnt work, but when I went to peel it off to send it back, it stuck to my tank + has ruined the glass. This company SHOULD PAY for my my time + my beautiful tank!!

Works great, a bit hard to read
