Tried the Silver 5D and 3D was not impressed. The 1.8 gain is just not there . I would say it looks closer to 1.1. They claim, this is ok for passive and active 3D. It may be ok for passive, it does not work with the active glasses. In fact, just viewing the material in 2D without any glasses and it appears to be much dimmer than my 1.3 fabric. Same for the 3D .product . Works with ambient light like the Black Diamond product , I'm not sure that is what it was
advertized to do or not, very confusing IMHO .
