The Samsung 3D glasses SSG-4100GB are currently the best quality / price ratio in 2012 (pdf 19,90e on Amazon included) they are lightweight (21g, battery included), very thin and with wide lenses to wrap up the vision, very pleasant to wear, we do not feel at all! I compared them with 3D glasses Samsung SSG-3050 that I had with my UE55ES6300 SSG-3050 weighs 31g (battery included), they are heavier and wider, we feel discomfort in the nose and they do not cover entirely the vision, wide brim do not help! but they fold and store in a case which is their strong point facing the SSG-4100GB which do not comply They are 20th but their output prices exploded from a certain time if it was the same price (ie 20th), my choice would be the SSG-4100GB because many much more pleasant to wear if you absolutely stand after they fold, the SSG-3050 Fast Search last thing: the strength equivalent to me, if we want to break them, they break! I hope this review will help you in your choice, why pay more ???
