WARP DRIVE PROTRACTOR

Forget about precision with this item. It is a flexible plastic piece of junk. The base is made of two pieces of plastic that are permanently fastened together. Unfortunately, for the unit I received, these did not match up well... such that the long edges that are used to read an angle are not aligned (i.e. two different flat edges for each side). If you dont have a smooth and consistent reference edge, you cant get a measurement that makes any sense. Dont waste your money on this item. Many better options out there.
