I work on very expensive electronics / machines that can cost $70,000. I know how to use all precision machine shop tools and a lot of lab equipment. No one here considers it normal that a precision instrument like this would light up the distortion light if its wires are bumped/ moved around/ or just in normal motion of use. So no I don't trust it ... but I wanted to come here and just see what the comments would be. Its going back to the seller. Shit happens but labeling me as some Poor SOB who is returning a working tool because of price isn't going to fly.
