Tried mine yesterday, with a 30" projection on a dirty-white wall from an Optoma gt720, well-lit room, mostly fluorescent lights. No sync or other functional issues; no crosstalk; colors were good; brightness was good (I expect it to be similar to the 100" gain 1.1 screen, bright mode, dark room). Spectacular 3d. Only problem was slipping/falling off, but I was looking down, the pj was on the floor; and the arms are short for my head/ears, this is a usual problem for me with all glasses. Overall very happy, especially after I just read there was no more discount on four pairs and less.
