Review on 🐠 6 Pack AQUANEAT Aquarium Thermometer - Reptile & Fish Tank Digital Thermometer with LCD Display for Terrarium Water Temperature Test by Alicia Mayne

Out of 6, 3 are within 1 degree of each other, 1 within 2 degrees, 1 within 20 degrees. Three of them were within 0.5 degrees of the ice water test. I haven't tried 6 yet. The screen is very easy to read. I got an extra L44 battery for each. The suction cups on the main body are pretty mediocre, they don't stick much (the whiteboard worked) and fall out of the slot that attaches them to the main body. . The sensor cable comes out in a corner, which is very annoying since you can't attach it to the front or side edge. It is worth proving in a large room that there was a difference of 3-4 degrees.
