Product according to the description. It's big and it ended up hurting the nose. For the rest it is a technologically simple product so not much to say. It flashes 2 small LCDs 2 balls with a small power supply on the side and an IR receiver .... Not enough to pay dearly for this kind of gear. Especially as the active 3D it is not there yet .... I want to my eyes and I still have time to wear glasses! Deeply in 5 years as techno moves :-)
