Query: General Tools 29 Plastic Protractor - Not great

I agree with "You get what you pay for". You have to be fiddle just to make sure the arms are flush against your workpiece, and then spend time second-guessing the reading that you see. The size of this protractor is convenient, and it's easy to adapt from inner to outer angles, but again, it's just too cheap to be used for serious woodworking. After 12 cuts trying to achieve a perfect 30 degree angle, I'm going to look for something a little more (hopefully a LOT more) reliable, and pay the $ for it!
