Two weeks ago I changed my old Viera Plasma for a new Viera Neoplasma 3D 50.
Since they didn't come with shutter glasses I had to buy them separately. So I started hunting for bargains but also wanted to try the original Panasonic ones.
Finally I decided on one pair of Panasonic TY-EW3D3ME for the (rather high) retail price, a pair of Panasonic TY-EW3D10 on a bargain, since they are phased out and they looked the most comfortable over my prescription glasses. And finally a pair of Xpand X103 Universal glasses.
Well to make a long story short, The special over my own glasses Panasonic one was a disappointment, so that's one for the guests!
The other Panasonic was ok but the Xpand glasses who were also the cheapest turned out to be the best by far. Field of vision and wearing comfort outperformed the original Panasonic glasses. The only thing that can be said for them, is that the Panasonic's look more fashionable.
