Many of the reviews that I read suggest that they may be a little expensive and they are not the highest rated so they may not be the best value. Some of the pros are the good viewing angles, excellant picture quality, great color and details, anti blur feature, etc. Some of the cons are the price and occasional issues with pixelation.
