Derby Black Outdoor Deutan Plano

A waste of money.

These don't work at all for me.

Good, stylish. Not that big of a difference in color, green and red are way better. Some yellows started to appear more orange with the glasses on.

New model cheaply made

I ordered this Derby model to replace an older Derby model from several years ago. These contain more plastic and are obviously more cheaply made. I doubt they will last as long as the last pair.
