I have bought for my 42lm620s of LG this Glasses (F315), they are really comfortable to wear even after several hours you can feel almost as soon as you are wearing, and the 3D is much more pleasant than with shutter glasses. But a little tip: I have had home 3 glasses are currently out of the cinema with me and have it tested directly on my TV, the result was that this is not at all different from the LG glasses and the movies they cost only 1 per piece. From the quality and size of the "glasses" you are almost the same. But I do not know if the glasses are different from cinema to cinema, but an attempt is worth it.
