I have that one too. I never trust the angle readings. Always use a combination square or a known previous square cut to set up the blade. Or for random angles (15, 30 etc), just make sure I cut all the angles cuts in one go. Cutting some angles, then going back to 90 and then trying to get that exact same angle again is nigh on impossible. But like you said, not fussed due to the cost.
