Edited-
Doesn't work. Urinated in container and tried two of them. They don't change color. Would not buy again.****EDIT- for some reason the five strips on the first sheet did not work, but when I tried the next page, they DID change color as they should. I'm guessing I just got a few faulty ones. Giving 4 stars since I got some faulty ones in there.

They do seem to work. When I put it ...
They do seem to work. When I put it on my skin it shows the correct temp. I haven't thoroughly tested it yet though, that's just my initial impression.

Pretty much defeats the purpose
I mean, it does work...but not through any containers. I even attached it to a paper cup with boiling water and it was not able to read through the paper. Pretty much defeats the purpose. It does work when I attach it to my forehead which may be useful one day haha

No color change at all
We tried three of these and none of them worked at all. There was absolutely no change of color. Very disappointing.
