So flux ordered two of these 3D glasses, which all went smoothly as far as (one of the glasses, however, appeared to be a back runner, had somehow been unpacked).
Then the glasses: By design, OK (although I know of no other active 3D glasses and therefore can not really compare) and seated himself very convenient for me as wearing glasses on his nose.
The processing is, however, the first deduction. While glasses frame and the built-in batteries valuable aspect, the two brackets are mounted to the frame extremely soggy. The temple look very cheap and far from stable. Whether the so keep a long time, be times undecided, here I would have liked thicker, more solid bracket.
Function: The second star deduction based on the fact that even in moderate sunlight eyeglasses both apparently come from the concept of 3D and 2D to constantly back and forth (!). One moves with his head again a little closer towards television, the 3D image can be seen again. I've tried from different distances. Again, please note again that I have tested so far no other active glasses -vllt are those glasses just so sensitive, I find it disturbing, however, eventually will not only in the dark watching 3D movies.
In low light conditions or even at night, the glasses are working properly, the 3D effect (tested with "Star Trek: Into Darkness") is impressive and accomplished theater quality.
Conclusion: Given the high price and because the glasses come from the same manufacturer of your TV, you should expect very good quality in terms of appearance, workmanship and function; however, this is given here only partially, hence only 3 stars.
