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.

Ordered a pack of 6 and they arrived sealed in a styrene see-through envelope in perfect condition.I need a flashlight to see the shaded temperature reading which is no problem - they are cheaper because they are stick-ons. I find them to be accurate and reliable, I especially like that they are easy to take off w/o leaving a sticky/filmy residue.

It adheres just fine but as others have mentioned, you have to shine a light to see it. In my case, it's showing 2 different temperatures, both of which are inaccurate. I tested with 2 different meat thermometers and both showed 78 as the tank temp. If it sounds too good to be true...Save yourself the time and effort. Now I have to peel the thing off and take it a drop off location if I want to get $5 back.

I've used several different brands of stick-on thermometer strips. These are the worst in terms of readability. They seem to be accurate but I find them virtually unusable due to the difficulty in reading them.

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.

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.
