It's my first DLP-Link glasses next to a children's glasses for my daughter. Beamer is a Benq W700 and the glasses does so immediately. In the 2 weeks, in which I use them there were no problems with synchronization or something sont. The 3D image is very compelling. I read often that there can be ghosting with the glasses and also that it is technically impossible. Now, the experience that I have done is impossible or not, it can really give ghosting. If one turns with my glasses head to the side and looks at the picture of the corner of my eye, you can see at the left edge diplopia as if the area would not close 100% strength. There are estimated only 5% of the area. But if the screen ausfühlt the entire range of glasses (which is not the case with me), may cause harmful interference. The image itself, I have compared with the through the eyes of my daughter, the contrast was slightly better in the children glasses. Overall, I'm very pleased for the price. The glasses are comfortable to wear, even for a non-eyeglass wearers like me. The picture is very bright and the colors come over very well. The mentioned Ghosting occurs only under requirements to which do not occur during normal film shows. I would buy them again at any time.
