Have been very pleased with these 3D glasses that I can complain a bit on is that you get a little pain behind the ears and the nose when you have them on.
+ Provides a very good and virtually crosstalk free 3D experience with my Epson tw9000.
+ That one will fit easily with their regular glasses, good for us to o from need glasses or for those who still need it.
+ Battery time is amazing on these, I've had mine for almost 18 months and have not changed the battery yet.
- / + Not as comfortable and easy as Panasonic ty-ew3d3 .. is. But they enclose better so not ambient light coming into the field of view so easily.
