Review on Enhance Precision Measurements with INSIZE 6140 Depth Base Attachment by Robert Xayamonty

Reason for only 3 stars - incorrect product description, product dimensions. I wanted a 4" base. I received an INSIZE 6140 depth base 3" x 1.2" x .250 (width x height x thickness) S/N # 301208249. It's basically a 3" base, isn't it the 4.2" base in the description. Otherwise the quality is good. Made in China!
