Review: Cheap, Cheerful and Accurate - Its quite cheap in cose, but the LED like display is nice and bright and my testing with my heat pen and other themometers show this is pretty much spot on for accuracy. The leadss are short (1m for probe, 1m for USB) so you need to ensure you measure the distance as required. But it works as desgined, and does not cost the earth.

A1 great digital thermometer

### ⭐⭐⭐⭐⭐ This is great i love it.
*by N***W on 3 July 2023*

I have two. These colour thermometers need USB power and nothing else. Having two I can confirm that they are calibrated the same as they read the same when placed in the same tank. just for you dear reader i got my expensive Thermo Pen One I use for cooking and stuck it in my tanks. KETOTEK Digital Thermometer DC 4V~25V, USB Power Supply Aquarium Thermometer was 23.1 degrees and the Thermo pen said 23 degrees and the same difference in the other tank. If you need more accuracy than that then God help you and your fish. One of my Kekoteks is over two years old. The glow from them is quite comforting or disturbing depending if you like a really dark room. I love it. Bye
