I bought a few pairs of different brands sold on Amazon, and these glasses are those that give me the most satisfaction (use with BenQ W1070 +).: - They are bright, without (much) color drift (no pronounced yellow or green cast, for example) and maintaining good contrast. - They have good battery life (a charge lasts a number of movies). - The signal hardly picks (which is not the case with competing models that lose sync when one turns his head a little) - They are suitable for eyeglass wearers and well wrap ("leakage" of limited light) - The price is acceptable for quality
