Summary: The Samsung SSG-4100GB universal glasses are cheap and fine for casual use, but an uncomfortable fit and too-open design means 3D enthusiasts will want other primary glasses.
Pros: The Samsung SSG-4100GB glasses are inexpensive for active glasses and compatible with other brands of TVs thanks to the Full HD 3D standard. Pairing them with your TV is fairly straightforward, they don't require line-of-sight, and the battery lasts a long time.
Cons: The glasses are fairly flimsy, the arms are quite short, and the fit is uncomfortable, especially if you wear glasses. An open design lets in more ambient light and can hinder immersion. They're not rechargeable and require a coin battery.
