Purchased confidence given the customer reviews on this site. Tested with two long films ("The Hobbit, The Battle of Five Armies" and "Titanic") on 2 consecutive evenings: - First commissioning: easy, fast (before commissioning: small charge for a few minutes for safety) - Recognition / pairing: almost instantaneous: the first night, a pressure of a few seconds before being the TV and it tells me that it's OK - 2nd evening: one (short) pressure on a button is enough - Hold the load: no problem (after 2 long movies) - They automatically disconnect a few minutes after being removed from the skull - Quality 3D vision: PERFECT !!! - Angle of vision: unlike some reviews here, and after verification, the glasses are not larger than the original glasses provided with Samsung TVs, but given the quality of the 3D vision immersion is total! I wear glasses and I watched these two movies with my headphones; Obviously, eyeglasses + 3D glasses + helmet: it's a lot of things on the head !!! well anyway I could hold all the time of these two films! Of course it cinches but it is quite bearable. Incidentally I highly recommend TITANIC in 3D version: the restoration work and especially 2D to 3D conversion is remarkable! Not many effects "before objects that are projected in the face" but a beautiful job on the depth; some images are truly sublime, at times it seems that the film has been designed especially for 3D! The band also beautiful, some effects are impressive clarity.
