The glasses are super lightweight and very comfortable. Tested with a 47PFL7656K and Gran Turismo 5 CoD Black Ops! Works beautifully and is great fun with friends or girlfriend to play together on the entire screen. The reduced resolution in split screen of course does not improve, as this is dictated by the console and the game and the TV only the split screen on the entire screen "converts"; the "Glasses" do the rest. Even without dual view eyeglasses can try it at home with an ordinary polarized glasses. Just keep an eye, the left eye sees almost one and the right eye the other player screen. Negative should be mentioned in any case the price. The glasses have no special super technology that would justify the price, only the difference to the normal, cheap polarized glasses in my opinion is that you have the same glasses in a spectacle, the second spectacle has 2 identical glasses of the other polarization. Could one therefore tinker with cheap glasses also myself;) Therefore, there are 1 star deduction!
