Query: Seemed to be rotting in warehouse.

Received them few hours back . These look like a very old product. The frame doesnt open smoothly, Opening and closing movement is rough as in many cheap shades. The lenses were dusty when i opened the product. Tested them for sometime. Not sure how good the modulator property is. They seemed to darken little bit in sun.I have bolle recoil red and black TNS bought in amazon.They are pretty good,frame is smooth and look new.I feel bad about buying these even after reading two bad reviews. Others BEWARE.I gave this product one star because it is still useful. I may return this product soon.pros:1)Price is good.Cons:1)Product is old.(May be not used)2)Frame is very rough.3)This product needs oiling at frame joints.4)The lenses become foggy.
