We are very happy with the glasses. Our LED TV from Grundig has decided to also buy glasses, which are also of Grundig. We had bought us by another company 2 glasses and were not good. Sex movies. In the Grundig 3 D glasses you have a clear view and Horny 3 D effects. Glasses from the delivery of the glasses was perfect and 1-2 business days since. I would buy again at any time.
