Horizontal Stick On Thermometer Strip, Digital Temperature Display for Fermenting, Brewing, Wine, Beer, Kombucha or Aquariums. 50-90F (10-32C) Adhesive Sticker 5 or 10 Pack (5)

Easy to use, seems pretty accurate. I use it on my kombucha brewing jar and keep temp around 82 degrees.

These thermometer strips are an affordable and convenient way to monitor temperatures for fermentation. I use them for kombucha brewing, and they stick well to my glass jars. The readings are clear and easy to read, and they work just as expected. The only drawback is that the temperature increments are grouped together, so you don’t get super precise readings. That said, for the price, they’re a great solution for general temperature monitoring. If you need an exact temperature down to the degree, you might want a digital option, but for quick reference, these work great!

Work great! Not as sticky as id hoped but they are getting a little wet here and there. Not often but enough. Most of them are great but the surface has to be flat! I love them though. They read fine

So my son received a Sea Monkey kit for Christmas. These are supposed to be the world's 2nd easiest pet I believe....well I'm not sure about that. The instructions say the water, which you put inside a very tiny plastic tank, is supposed to be in the 80+ degree range for these lil suckers to hatch. I'm not sure how you're supposed to know the temp since you're warned not to put a thermometer inside the tank. After several days of no hatching, lots of panicked momma research, lots of obsessing by my Autistic son....these stick on thermometers were on the way!! They helped immensely and worked within seconds to let us know we needed to warm up the water a tad! My son could easily follow the color grid and find our where the temp was at, which he loved!! Thanks for a great product!!!

These thermometers are accurate and easy to apply. I use them for my 1 gallon carboys.

Recently, I decided to get into baking sourdough bread and found out that it would be good to have this type of thermometer on the jar with the sourdough starter, since the temperatures are very important for having success with sourdough. The thermometer is very easy to apply via the sticky backside. However, it appears that they tend not to stick perfectly to the glass. On one side the end did not lay down. No biggie, I use rubber bands to mark the volume of the starter, so I just put another one over the thermometer. Time will tell if they hold up being handled often and also when they get wiped down. It is undoubtedly VERY helpful to be able to see the temperature right there on the vessel you use for your project.

I like that you get 3 thermometer strips. The strips are easy to read, meaning that the colored numbers are visible. And it is easy to adhere to a 1 gallon glass pitcher. I had to reposition one and the sticky residue is strong and thick, making it easy to move and reapply. Definitely recommend this set!

Work well. Accurate and all appear consistent. So far....
