$40? - that is a VAMO, not a cheap clone of a VAMO.
Carhartts - Tough work pants. More like ANTI-fashion. Probably with a pocket for your ProVari.
And I use my VAMO and SVD too, so they won't be sad - but I don't use VW anymore, because I'm more aware of my preferred starting VOLTAGE now, with all my juices and toppers...and it works out the same. Start at a setting and tweak it a little to taste.
"set and forget" just doesn't work because of variables like
juice, humidity, temperature, altitude, whether dinner was spicy, my mood, the alignment of the moons...as long as I can adjust SOMETHING, all is good.
