I received my 3D glasses in a very short time (8 days), I have ordered a pair, not wanting to take any risks despite the comments in general very supportive of this. I obviously tested on these glasses, and remarkably, setting 3d screen on my Panasonic, immediate, not a qualitative difference ounce with those I have and worth a whopping 179 !!!! Light perfectly, no problems over my glasses, they are a very good comfort. Certainly the quality of the plastic is a little basic, but and it is not the essenciel, they work perfectly, do not darken much beside the ones I use, in short, total satisfaction, I will therefore be able to recommend at least one other pair. One downside: lack of instruction in French, very embarrassing for me. Will he get a site where said notice in our language?
