Aquarium Thermometer,Betta Fish Tank Thermometer Sticker Adhesive Thermometer Strip 3 Pieces

Used these for my kombucha jars and they work great!

While not the intended use, these self adhesive thermometers on a plastic bottle full of “water” that I need to keep it 98.6°. I did have a more accurate but smaller range temperature strip, however it only went from 90° to 100° and didn’t indicate above 100°F so these came in handy to see how much above it actually was.Stickers arrived in good condition and all four were there and all worked exactly as described. The colors are not as bright in person, but that is the same for all of these liquid crystal displays so you can’t hold that against this product. As far as aquarium temp sensors - I’d say if you have the option, a fish tank thermometer that goes inside the water will be more accurate but this is always a low profile good way to get a rough idea of the tank temperature.Overall it’s exactly what I expected and arrived exactly as described. Overall A++ and would buy again for my needs!

Seem to work well enough likely working within the specified error margin plus minus a degree or two. This if fine for me I mainly just use these to alert me to any potential heater malfunctions. Most heaters are designed to fail in the off position with the use of spring loaded contacts. However these can be faulty or contacts can weld closed. So be on the Safe side stick these opposite to the heater and give it a look every day or so. They work well enough for this application if you need much finer control then you'll need to buy a calibratable thermometer that's been verified to work within its specified error range.

Stopped working after a couple of days and water leaked inside

Did the job on our small tanks. Colors are hard to see so readability is difficult. Installation was easy and adhesive is high quality. Clean appearance.

Slap them anywhere and they work pretty well. I use these on my fish tank, snake tank, And when we have baby chickens for lamp heat. I’ve compared them side-by-side to other more expensive thermometers and they are always very close within 1-2 degrees

Tells the temp of our tanks. Sticks well to the glass

The product sticks to the tank very well. It is a little dark to see what the temperature indicator says for the temperature, but it does work. I have used it for a while and have no complaints.
