But big plus:
the G15 was next to my dear ZD301 the only glasses that showed in Gravity no ghosting. My Benq and also ordered from Amazon "Cinemax Hi-Shock Active Series" have shown almost the whole movie diplopia. What has disturbed me very personally, my friends, but rather less. Otherwise, I would find the latter to be in all other respects better (except price of course, as the G15 is probably unbeatable). In other films I have none of the glasses may find this effect really doll, but I'm not an expert.
So:
+ Price
+ No ghosting at Gravity
- A bit uncomfortable
- Small glasses
- Strap can not be folded
Although only 2 pluses and 3 minuses ... but the first two are clearly more: D so 4 stars
