Skil Digital Angle Finder: huge mistake!

Ok, I may be having a huge brainfart on this, so you tell me.Skil Digital Angle Finder - Model #2100DAFI bought this thing and used it this week for some trim work at a studiowhich has lots of non-standard wall angles.It measures angles fine. The problem comes in converting miter angles onobtuse angles. Acute angle are fine. If the angle of the corner is 89degrees, the miter reading displays 44.5 degrees.But if the angle of the corner is 91 degrees, the miter reading alsodisplays 44.5 degrees. Shouldn't this be 45.5? If it?s 100 degrees themiter reading will display 40 degrees. Shouldn't this be 50 degrees?I can only guess that the computer was programed to calculate the angleon the other side of the right angle, or between 90 and 180 degrees,instead the obtuse angle.This makes the devise useless in my book. Now before you go and say,?well, all you have to do it subtract the angle from 180 and blah, blah,blah,? I bought the thing so I wouldn?t have to do the math. I paid 60bucks so I wouldn?t have to do any math, not even half of it.Am I losing my mind here, or is this a POS?
