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.
Review: great to use on your ps5 console - readability very clear functionality works great temperature seems to be reliable accuracy seems to be right

As an experienced fish keeper I appreciate when things just do what they should - this is a nice little temperature monitor that’s accurate and easy to read. The only downside is the usb lead as per other reviews was a little short.
