I had bought for my Panasonic projector (PT-AT 6000) a few Samsung glasses because was nowhere clearly identified, which support 3D standard projector. I had to find that infrared goggles are required for the projector, take the Bluetooth glasses that I had ordered. Four of these glasses have me Ca. 60 tasted. For these glasses I have paid more than 70. For the price it was then only 2 glasses. Why glasses with outdated IR technology must be so expensive, do not open up to me. The price-performance ratio is so abysmal.
After all, it is very easy and makes a stable impression.
