Review on ChgImposs Stainless Protractor Adjustable Double Arm by Riley Skeet

Thanks to my knowledge gained in practice, i was excited to try this Industrial and Scientific protractor for my next project. However, I found it to be unreliable and difficult to use .The arms would not stay in place, resulting in inaccurate measurements and frustration in my work. The only pro was that it looked and felt sturdy. Overall, I would not recommend this product..
