Ive got lots of snap on kit and have to say its not all the mutts nuts and going by my workmates snap on multi meter last night they arent no good either!
Any laser temp tool will not work on anything shiny for example brake discs you have to take readings off of the rusty bits on the edges.
Mines some old thing I bought years ago I always check my hand temp and then the floor temp as a datum and away we go.

The same laser temp gauge worked just fine when I did the oils on my discovery ZF gearbox, it hasnt blown up yet two years later
