Query: Denali 11" Digital Angle Protractor not worth purchase

Product arrived 7 degrees off zero (when closed, display read "7.2" degrees). Horizontal spirit level was 1/4 bubble off plumb. No way to reset the display, and the battery impossible to remove. I managed to disassemble the protractor and bend the contacts (electrical pick-up in the handle) so it read zero ("0") when closed, however, when checking angles with a real protractors set at standard 90 and 45 degree settings the tool was .2 to .3 degrees over. If you're using this for a hobby or novelty item it might be okay, but if you try to use it for it's intended purpose you will be disappointed. I wouldn't even use it around the house for general woodworking projects, let alone in the construction trade. Giving it a "one star" rating is being generous.
