This is my '73 Super Adjustable I got about a few months ago, and have not shaved with. The reason is that it looks like the blade gap is uneven on one side. It's most obvious (to me anyways) when its set on 7, which is what its set on in the picture. I hope I'm just seeing things, because I'd really love to try this razor out, I just don't want to chew my face up in the process. It's strictly a user-grade razor otherwise, with quite a few flea bites on the head. But the adjuster clicks nice and solid, and the lock-down knob works perfectly, too.
