Best praise vs top criticism for Anker Nebula Mars 3
“My Mars 3 Air is apparently only 400 lumens and it’s plenty bright enough in the evening / night https://preview.redd.it/2cbcnus1r2bg1.jpeg?width=4284&format=pjpg&auto=webp&s=f53968b72e5342dd7aa7ae6f455762c8034cf408”
“If no battery is required i would get the 4k SE. Also the Netflix experience is better as it's certified and not a mobile app with mouse functionality compared to the mars 3.”
