You know as well as I do that there are 2 kinds of active glasses available for T.V., for ex: one that you can charge via a USB port and the other that requires a small battery, you can calculate the times of usage to charge either one, are they a bit more expensive, YES, do you need to be more cautious than the other passive-polarize cheap ones, YES, can you actually notice any other object in the view field flickering?...well I never had that issue. Proudness, happiness, satisfaction, luck...I just hope the T.V. last another 5 years.
