Works great. It agrees with what my CHT, and EGT temps are showing, sitting in the shop. My plane is an experimental,, with removable wings. They suggest mounting this in the wing, outside the propeller arc. This probe, is so small, I mounted mine, behind the spinner.

Updated probe is easy to install with threaded attachment including nut, washer and but splice connectors installed on the probe leads

To be able to see how cold you are is very important. As in look honey we really are cold it is 32 degrees outside and look our true airspeed is...

Was easy to install and wire. Seems to consistently read between 4-12 degrees F high in all conditions. Havent figured out a way to calibrate. Wanted it mostly to determine exact freezing level when flying IFR. Useless for that. I think its just a token temperature reading that looks cool on the display but will need to continue using my old Scott OAT probe instead.

Probe is small and easy to install but the leads are too short. We needed to cut one of the butt splices off due to our install sequencing error and it didnt leave much wire for re-crimping

Leads are short and does not provide a method of mounting the probe--its just a cylinder without flange (and threaded section for capture nut). Lack of mounting method makes it difficult to use.
