I just got my pair of the Estar ESG601 3d glasses. Best dlp link glasses that I have tried. I own several other brands mentioned in this thread but these are superior. Here's what I've found:
1) Greatly reduced ghosting. The only time a see faint ghosting is when playing 3d games with a black screen with a small bright area on it.
2) Sync. I haven't lost sync once yet. The other glasses I would lose sync at least a few times in each movie.
3) Flicker. To me this one is huge since I play 3d games with my pc. Usually I can only play for 2 hours and my eyes get tired. With the Estar it's like I'm not even wearing 3d glasses as far as eye strain goes. One little test is turning on a cfl light bulb with the glasses on. With other glasses you can see flicker. With the Estar I can't. I watched a 2 hour 3d movie then played various 3d video games for 4 more hours and didn't get eye fatigue that I noticed.
The comfort is fine. The brightness is average. The only negative I noticed initially were reflections. Just don't have anything that reflects light behind you. If you are watching a projector you probably don't want reflective surfaces in your room anyway.
I highly recommend these glasses especially if you are a heavy 3d user.
