These glasses have been mentioned before. Can anyone tell me about them? Opinions good or bad? This is the item I'm looking at- I like the price: Accupix Mybud 3D Glasses Color Black Present a 110V Adaptor 186*167*44mm Would this package include the "dummy glasses"? For that matter, how do dummy glasses work- do you take them to an eyeglass place? Thanks for any help!
