Uttam,
My experience has been good.
1. After some initial confusion, I could get the glasses to work by pressing the button above the nose bridge of the glass. You need to get used to the glasses, especially if you are putting them on over your current glasses.
2. 3D glasses require a certain minimum distance to be maintained between the viewer and the screen. If you dont, then you will get eye strain and lack of 3d depth.
3.Proper 3D experience depends upon the source material. BD MKV rips are not alwayS good. You need to have a proper 3D Bluray disk to assess your glasses. Try IMax Disk and you will enjoy 3D.
4. If you are ordering 3D Sainsonic glasses, make sure they are rechargeable. Otherwise your glasses will be a big waste.
5. brightness of the image will reduce considerably when playing 3D source, but with Sainsonic glasses, this brightness drop was not very much. My BenQ W1070 does a good job of 3D.
6.IF YOU ARE PLAYING MKV BD RIPS, THROUGH MEDIA PLAYERS SUCH AS WDTV-LIVE, MAKE SURE TO SET RESOLUTION OF THE PLAYER TO 1080i, ELSE YOU WONT GET SBS 3D TO PLAY ON W1070.
7. Finally, you need to be a little patient with yourself to get 3D going and to come to enjoy it.
