Well, i posted something along these lines earlier, but i'm doing it again.
My 4 pairs of monster glasses have great fit and performance, but i'm having SERIOUS issues with battery life.
3 of the 4 pairs last a movie, maybe 2, and then i have to charge them again. Even if i watch 1 3d movie a week, that means i have to charge them every 2 weeks. My factory Sony glasses do not have this problem. I've only charged them once, and i've had my projector for a year. MInd you I don't use them as much, but i bet they would last 15 movies or more.
As for my fourth pair, well, they won't charge or power on anymore. WTF
So i have 4 pair that either don't hold a charge, or won't work. Does nobody else have this problem? i've tried different chargers and cables, and no matter what, this is how long they last.
