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.

I have that same Snap On light that I can not use with my MSD ignition. Timing mark is all over the place. Bought the cheapo Flaming River and the problem was gone.
