Review on Caution Maximum Write SmartSign Aluminum by Brett Williams

As an INDUSTRIAL and scientific worker, i was highly disappointed in the effectiveness of this safety sign. As a result of my tests I determined that the combination of small font and lack of reflective material made this sign practically invisible. The only pro is that it is made of aluminum... However, this is outweighed by the con that it fails to accomplish its intended purpose of warning workers of potential hazards. Save your money and invest in a better product for occupational health & safety..
