They work!
These do work. I had a couple of cold nights of mid 40's and the leaves scattered throughout the house were brown. Turn on the heat and they soon turned green. I touched one and my 96.8 degree hand turned the leaf yellow. The kitchen leaf turns a yellowish green when cooking. Finding a neutral temp place for the leaves were my biggest task. I found it best to place on wood, plastic, book or cardboard surfaces. Glass or the wall is too cold for an accurate representation temp.

Dog approve
Worked as advertised. Too bad only a couple survived when my dog ate the package.

Watch leaves change color more often than once a year
Lovely thing - a useful (yes, it sounds like an oxymoron) decoration. Allows you to visualize the temperature in the room in a very natural way - if hot, then the leaves turn yellow, and if it is cold, the leaves go brown or even black (as if frostbitten).
