I use these to fix electronics.
Got these and was disappointed because they would not change color. I set them aside planning on returning them. The next time I picked them up, they worked, just as they should. I use them one electronic circuit boards to find the hot spots. Example: When something fails after running for a while, it's probably a heat problem. These sheets will find the location of the heat. The part under the sheet is either defective, needs a fan or heat sink. Often aheat snk will solve the problem.

Total disappointment.
Save your money. These will barely react for 1-2 days out of the packaging and then they become useless. I bought them to add to my sensory wall in my classroom, total disappointment.

Works as intended
Exactly what I expected, It's a thermal sheet like any other one. I use this to demonstrate heat transfer. Is it like the photos? NO, but if you ever owned somthing like this, then you wouldn't be surprised. Photos are definitely misleading, that is why I dropped it a star. Overall it works as intended.

Did not work as shown
This did not work. I only noticed color changes if I had the paper sandwiched between both my hands but that is not the use that was described. It worked nothing like the photos.

Activation temperature much higher than advertised (>40°C)
I love thermochromic sheets and use them when I teach. These sheets work great- if you have a blow torch. The activation temperature was well above body temperature (certainly above 40°C), and definitely not the 24-34°C advertised. I presume all the reviews said they "didn't work" because no one tested them with hot enough temperatures. A propane torch for cooking did activate them easily enough, and they showed a good color range when I did so. It's a good price for hot applications, but useless for any body temperature stuff, contrary to how it was advertised. I speculate that this mistake for temperature range was a mistake in the mixture chemistry used to create it.
