Review on 🌡️ UCTRONICS K-Type Thermocouple Temp Sensor: Digital Temperature Meter with Blue LED Display and Black Case by John Mceachern

Please note the black plastic case was scratched below the numbers: I was surprised to find it was carefully packed with foam at each end of the box but came without a protective film the front counter. Apart from that it seems to work fine - conveniently it also runs under 12V so I didn't need an extra power supply and just ran it from a 5V Raspberry Pi (3V works too but is too weak). As others have mentioned, it's usually dim (even at 12V) but I have another brand that shows the same brightness so it's exactly what I expected.
