2-Pack Aquarium Thermometer, Fish Tank Thermometer, AikTryee Water Thermomete...

I use this on my pond to keep track of the water temperature. Works really well for this.

This pair of digital thermometers came with 2 extra button batteries and 2 extra suction cups for attaching tank sensors. I've used them for over a month and have only the best to say about them. They update the reading about every 10-15 seconds. They make it very easy to monitor my aquarium temps to keep my baby turtles in a safe range. Inexpensive but they work great.

Accurate, but it's cheaply made & may not hold up: I CAN'T see this holding up to NORMAL use or taking being dropped a lot.

So Glad I got these for my Aquarium. I have one on each side of the aquarium to manage tank temp. I found out My heater was not staying at a consistent temp. I was able to get a new heater before stressing my fish more. Happy aquarium now~

Using them I found my new rwhirlpool efrigerator that came set on the recommended temperature was off by 15 to 20 degrees. Fridge was running 45 to 46 and the freezer was running at around 32 to 36 which is above fda recommended Temps. So I pushed the button for highest setting and it works fine now. Size easily inserts in to freezer. Accurate temperature reading. Bright lcd screen easy to read

Reads about 1.5 degrees high. Used an instant read thermometer to get the real temperature and on both temperature units they were both about a degree and a half high so when you look at the temperature, you have to subtract one and a half to know what the real temperature is. It should be able to tell the temperature it’s the only thing it does.

small and convenient to use comes with a suction cup on the wire so it doesnt just fall off

I use for my refrigerator in My rv. Seem to be accurate. Work well and easy to read

The thermometers that I received were so inaccurate as to be useless for use in my aquarium. Returned.
