I ordered these to check the efficiency of my heaters. They work great and just like a mood ring. Great value.

Great value easy to read if your not blind. Lol. I read comments like how hard it is to read. I have no issues. But also my fish room is well lit. So if your in a dark room I could see how it would be difficult. But I like them and I'll buy more as I expand my room. I bought 30 of these. Again no issues. Also the key thing to do is rub your finger up and down the thermometer to make sure it is fully adhered to the aquarium for best most accurate results and make sure its not over the silicone on corner of tanks as the silicone will prevent accuracy.

Perfectly accurate when I compared to the standard bulb thermometers that sit in my multiple tanks. I also like that these go lower into the 60s than other comparable that only go to the low 70s because I don't run heaters in any of my freshwater tanks, so I need to monitor temps more closely in the winter. The only thing I don't like is that they're hard to read without shining a light directly on them.

Perfect if you need to limit or the temperature in several rooms. Since these stick on any surface, you can put them in not so visible places too, like behind a door

Easy to read, with the colored squares. Easy to apply, just slap it on the glass. Good price for 20 pieces, but that ended up being a large quantity. I thought I would have to use a new sticker every time I washed my carboys, but they stuck on through washing and sanitizing just fine.

Pretty much all black. Very little indication of a temperature reading. You have to really look hard, and then it's so faint you have no faith in the accuracy. I cannot recommend.

Cant read the temperature at all. It doesn't light up at all. Have to use a torch and then barely can you see the temperature number. A total waste of money.
