Just used this system on my new Philips 3d ready TV. Great quality.Very little cross and with good 3d sources crosstalk is barely noticeable. Glasses power on and off automatically (that is a plus). The build of the glasses feels solid.
Did not give five stars for the following reasons:
1 No possibility to recharge specs via USB you need to buy lithium batteries.
2 No 2d to 3d conversion applicable (though I suppose it's more a TV issue not the glasses).
Otherwise it's a great product. highly recommended!
