I got 1 goggles when buying my LC70LE740 "to".
Another So I then bought here, and two more on amazon.uk.
From a technical perspective, the glasses are really good!
Super image and clever solutions:
The charging time is ok, the service life (up to 30 hrs.) Really good.
What I really like is the possibility to switch a 3D to 2D.
For someone who might in 3D is bad or gets a headache from simply switch to 2D, and the others can continue to enjoy 3D.
Because apparently someone has been thinking in the development department ... ;-)
One point I draw from because the glasses with me, as with some other also, quite far forward sitting on the nose, which is by no later than 1 hour. Unpleasant.
Then I start getting to the spectacles on his nose back and forth to Schiben .... that sucks a bit and clouds the viewing pleasure.
On the other hand, it would annoy me a lot more when the picture was bad.
Conclusion:
A very good spectacle for those who have the appropriate headers and / or nose shape ... ;-)
