I watched my old video on the differences between Gen 1 and Gen 2, and I didn't seem to notice anything regarding the "Made in USA" phrase. The primary changes are:
Gen 1 = No pads, and on the back, the details are only indentations
Gen 2 = Embedded pads, and the details on the back are complete holes that go through the frame
Generally build quality will be a better indicator of the genuine pair vs a fake. - Dann
I wached you video, many thanks for your explication, is very rare this situatios, the quality is very good, same material, but with out "made in usa" :C
