Aquarium Thermometer Strips, Adhesive Kombucha Beer Brewing Temperature Strip, Stick On Strip Thermometer Sticker for Fish Tank/Fermentation Jar (39 to 97℉/4 to 36℃) Terrarium Water Temperature Test

Works great. Nice size. Easy to see numbers.

Fairly accurate

This is a correction/replacement to my previous review. They actually work. The temp can be a hard to see unless your eyes are at the same level as the strips. I have the strips on a jar on the floor so when I tried to check the temp (even if I squatted down) I could see no color around any of temps. I took a picture from lower down (parallel to the floor) and suddenly the temp could be seen :-)

It’s Great work now I should let you know it’s great for my sourdough starter but it may be big for 300ml mason jars. It’s easy peel back of plastic and stick on to mason jar perfectly and best part literally for $10 dollar for 4 set for all jars accurate tempter logins.

Super easy to use. and quite accurate for the price.

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.
