Review on 📏 Enhanced Protractor for Accurate Carpenter Renovation Measurements by Jeff Rhodes

I bought this because of the good reviews but it's cheap. The center scale is not attached to either arm of the instrument, causing it to stay in place during the first two degrees of arm movement, causing all measurements to be off by up to two degrees, making this instrument useful for precise angle measurements becomes unusable. Tightening the rear plastic screw does not solve the problem and the fault can only be due to poor design.
