Just incase anyone is wondering whether or not they should fight like LARPERs to be on here when they are released next...
This tool is not great. Its is not good. And its certainly not mediocre. IT IS BRILLIANT!
I used mine once since I got it in April, boxed it up an shelved it. Two days ago I developed what I now have identified as a massive vacuum leak in the upper plenum of my LR Disco. I was stumped. Hooked up the harmonizer to the port, set it to guage, and voila... 3" instead of the normal 20-ish. Cigar smoked it and sure enough- pinched wire between upper and lower mating surfaces.
So others may live...
