The verdict

Why it scored a 79

At $519.99, the Nebula Mars 3 Air is a battery portable that doubles the Capsule 3's brightness at 400 ANSI lumens, with Google TV, Netflix and dual 8 W Dolby Audio speakers. Satisfaction leads at 86, Reliability follows at 84 and Features reach 82 thanks to the 2.5-hour movie battery and Bluetooth speaker mode. Quality sits at 78 because it is larger than the Capsule and offers no optical zoom, so placement means moving the unit, and the one-year warranty holds at 55. It is the backyard-movie pick for families who want a full film on one charge without running an extension cord.
