I think you should have taken off the screen protector to make any comments on scratch ability, in all fairness any meter left in Auto will be slower to work out what you are doing rather than manually setting the mode, perspective these are around $30 AU delivered so they are good just for having in the glovebox of the car, saying that the kaiweets is also branded as GVDA and Habotest, the Habotest HT124 is $14 delivered to AU so is probably the better one to have in the car
