Review on 🔎 Precision Alignment Tool Mirror for Turntable Phono Cartridge Stylus by George Jacobson

The instructions on the back are IDIOUS!1. Place the protractor on the turntable spindle.2. Move the protractor and hand so that the needle is directly over point "A".3. Move the protractor until the cross lines are parallel to the sides of the cartridge. (WHAT?) 4. Repeat steps 2 and 3 above "B".5. If the OBSERVED ANGLE at "B" does not match the ANGLE at "A", rock the cartridge back and forth and rotate the cartridge the same angle at "A" and "B". (WHAT ANGLE?) Totally useless guide. Useless if they can't even put together coherent instructions for their product.
