Aquarium Thermometer Sticker Fish Tank Temperature Sticker Brewing Thermometer Strip Adhesive Thermometer Sticker for Fish Tank Storage Tank Wine Jar by AikTryee

If the temperature is between numbers (ex: currently reading 79°F) the segment's temperatures don't overlap enough to be clearly visible - you have to stop and look closely. My cheap floating glass thermometer is reading 80°F, so accuracy seems fine.

What a great deal! I am very happy with these peel & stick thermometer strips. I mainly go them for my home brewing keg, as well as my computer case to get a better room temperature check. Right from the package, they were reading the temp of my hand. Peeling off the backing was very easy, & I knew right where I wanted to put it to stay for a long time. I cut one of them, so it would fit my Lexan brand brewing keg. It's doing a fine job for me. For the most part, I can see the temps ok, usually I need to have a light on to see it, like others have mentioned. I will say that it isn't always blue green brown, but pretty close. I wasn't looking to cook by it, nor forecast the weather, just get an idea of my brew temps. Be sure to clean off the item you're going to put it on, & give a press for a good seal, the adhesive is very good.

You get 5 for a nice price. East to stick on to anything and mostly accurate for a quick temperature reading. The colors don't show as well as they could. And it is just a few degrees off usually. But it mostly does what I need. Perfect for my small quarantine tank.

They are easy to read, and seem as accurate as all types of temp testers, including all the stick on and submersible digital testers, When I am unsure if there is a problem, These are the only ones I really trust.

I have 3 aquariums. Ordered the " six pack " Placed one on each tank as soon as they arrived. Two of them never registered anything ( the next day )and the third one was almost impossible to read without a flashlight and squinting very closely....... Also, be advised, they are hard to remove.

3 stars because they are handy to have, though imperfect. Hard to read without a flashlight but they work. I use them for Kombucha bottles/jars. The backing can be peeled off so that it will self-stick permanently. I tried to remove one from a jar and it fell apart so they are flimsy and not transferable, but you can tape them onto a jar without removing the backing if you want to transfer them to another jar later.

Exactly as described and expected, cheap alternative to other brands and work just as well, adhesive quality works perfectly too

Used on my 36 gallon aquarium. Sticks well and accurate. You get a pack of 5 and I still have the first one in use. I have an aquarium about 25 years old and has the first original thermometer still on it (don’t know the brand of it but it can’t be too different) and it works like the day I put it on there. If it goes bad, I have 4 more to fall back on.
