Used in my 36 gallon aquarium. Sticks well and accurately. You get a pack of 5 and I still use the first one. I have an aquarium that is about 25 years old with the first original thermometer still in it (don't know the brand but it can't be too different) and it works exactly as it did the day I put it there have. If anything goes wrong I have 4 more to come back to.
