Furthermore, I consider it a great advantage that you can turn on the glasses and passive - so that you can view the picture in 2D and the rest can continue watching 3D. There are people, which is a little uncomfortable in the long run but 3D and so do not settle the glasses and "abstain" on the film have.
Compared to the first generation, the "new" are also less heavy, which improves the wearing comfort enormously. Personally, I find even the nose bridge a lot better, this is not so close to my mind.
I would buy the glasses at any time and can therefore issue a strong buy recommendation.
