I bought 5 of these glasses to use with a Samsung PN64D7000 TV. I've had them for over 2.5 months now and they still work like a charm. Easy to use and easy to connect to your TV. Simply face the TV and press the power button on the glasses until it flashes red and green. Then wait for the TV to show a message that the glasses are connected and you're done. You don't have to turn off your glasses. When the 3D film ends and your television no longer transmits a 3D signal, your glasses switch off automatically as they are not receiving a 3D signal. You will see the power button on your glasses blink three times to turn them off. These glasses are very light and very well designed to fit both an adult face and my 5 year old son. They are also very affordable. Hence 4 stars from me. Would give 5 stars but the glasses don't have side panels so light comes through the sides. Maybe Samsung will fix this problem in the next model.
