WOOOOOOOW, need I say more about those glasses! I spent many order on Amazon, but this time I take the time to write the first comment. Not knowing LCS initially, I ordered 2 pairs of Sainsonic 904 for my projector Benq w1070. Blu-ray 3D first test and what about? stalls (3D signal loss), many inversions oeils right and left, a weight center front and glasses whose field of view is too small in height. Dissatisfied by this experience, I retry snooping again and falls on the LCS model. I had the son of Philip of LCS in the phone for a good 5 minutes, and I must say I have rarely seen such friendly shopkeeper, accurate and thoughtful answers in respect to his client; especially for an object that costs only 30 euros. In short a very positive experience. Glasses and received on that day and there: THE SLAP. Pretty glasses, balanced weight, simple but extremely effective. Signal top, better contrast, better dynamic image, the better field of vision, comfort. In short the best what. For a few euros more than competitors, you will have a model that perfectly hold water (at least on my DLPL model). As promised, here is my comment, admittedly a bit long but it's so deserved. A Big THANK YOU for I am a Satisfied Customer fully today.
