When you unpack the glasses & want to use immediately / long - forget it.
In fact, the suspension of the temple is completely inadequate and a disgrace for a TOSHIBA product !!!
BUT:
Just take two narrow cable tie, a pair of pliers and 10 minutes of your life values, then you get 3D glasses that deliver a class-synchronous, deep image, and not fly apart. Simply the cable tie possible to push far glasses center and then tighten them well.
I'll try to upload to view 3 pictures, then you certainly understand what I mean;)
The glasses have good levels of comfort are easily and even for eyeglass wearers better suited than the AG02G by Toshiba.
For the money and the small craft course the AG03G are the best, least expensive 3D glasses that I've found.
