Here not there much to report, and certainly nothing to complain about: The 3D shutter glasses came packaged very well with us. Unwrapped, charged (USB cable was) 3D Blu Ray started and amazed! Since we had a precaution only once ordered a single glasses, we will now probably 2 more order, so that our (small) family can participate in the closed 3D enjoyment. Disadvantages? actually no. Yes, except the price: about 60 euro's just a bit much ...
About long-term behavior can of course make any statement at the current time, maybe there times an addendum ..
