Low BrightnessDetails in dark images (photos/video) disappear (tested in a pitch black room, projecting onto white wall).I like my Mars 2, and I'll get some good use out of it,

Audio LagThere is no lag when playing videos via the built in Youtube app, but when videos are played through HDMI the audio lags about 0.25 seconds

Last note is the Netflix app available from the unofficial store is limited too poor quality 480p video, and you can clearly see the difference between built in and when running from a fireTv
