ProsLove the fit and finish on theseQuality of materials and workmanship is very high. Readjusting the bottom is a must.

OnlY worked for few months , cable started to damaged soon , not good for folding , not worth the money The head band is an extremely bouncy plastic (assumed based on weight). Also anywhere you mount that is only one layer of sheet metal thick bends like heck if put any weight on this thing. The next morning I woke up and my entire stomach and back were burnt. Bad hardware. The first time I got the lens, no complaints at all.
