At first I could not get these to work properly and I thought that the glasses were faulty, I was using a Sandisk ultra 8gb sd card and just could not get them to work.
After a while I thought it maybe the card so I used an old 1gb card, tried it and the glasses worked first go, then again and again, in fact they worked perfect even on a windows 8 computer which is not stated on the list of compatible operating systems. The video quality is good for the price and the 1gb card lasts about 28 minutes, so all I need is a larger capacity card similar to my old 1gb card for longer record time. The internal battery lasts about 2.5 hours after been fully charged
