It's a mystery to me why it apparently with almost all manufacturers is standard that 3D glasses very expensive, must be thick, black border and incredibly ugly. That there is an alternative, Sony impressively shows the TDGBR750 glasses.
The general advantages and disadvantages of glasses
Benefits:
+ It is not the ugliest of ugly glasses
+ Function well (no ghosting, not too dark)
+ The thickening on the bracket act in practice less powerful than in the picture
+ It is nice and light
+ Also sits on my huge head halfway comfortable
+ Rechargeable
+ Automatic shutdown
+ An extra use for eyeglass wearers is included
Disadvantages:
- Way too expensive; I appreciate the pure manufacturing costs to a maximum of 10
- The plastic material looks cheap, the hinges not very stable
- The glasses could be a bit bigger
- No protection against lateral scattered light
- Not suitable for small heads (children)
Because there are nicer and better glasses and I think that you could make at this level the price / performance ratio still substantially optimal (unfriendly terms, one could speak of exorbitant prices), I admit, despite flawless technical function only four stars.
