I still use a digital Snap-On unit and I checked it against the Flaming River unit and they were both dead on the same marks.
I used to use an old dial back Snap-On and I always trusted it but it quit and they don't repair them anymore. So I traded up to the Digital push button back around 18 years ago and it still works perfect.
