My auto service professional had a set on his desk when I went in to pick up my car last week. I guess it is the new norm?
I need a set on my desk for all the sales calls we get from those looking for that "magic" solution. "If I plug in your tool, will it tell me what to replace?"
These are widely used and accepted on just about any forum that I've visited or registered on over the last 3 decades or so.....
I also seen them being used at dealerships and other shops quite often....
