I've used this so many times since I bought it last year that I have to say it is one of the best investments I've made yet in tools. Versatile, practical, and spot on. I have yet to hammer the angle to shift the alignment as it's as spot on today as it was from the first time I've used it. For me personally, reading white numbers on a black background is better. Despite the slight shop abuse, the black coating is intact and no scratches yet have gone deep enough to the aluminum. Has all the conversions and measurements you'd need. Get this tough tool!
