The AAXA P300 Neo can do all of the same stuff as that M6 though, in terms of its media player, and has pretty much the same specs, save for the lumens, contrast ratio, and resolution. I will give this to the Neo: it has a longer battery life 2.5 hours to the M6’s 1.5 hours. So if running your portable projector on battery power is important to you, this is something to consider.
If you are willing to spend the $599 to get the M6, I would also suggest checking out some of the reviews on our Pocket Projectors category page.
As for Picos, I don’t know of a better $300 projector. I’m reviewing the Acer C200, another Pico, and I’m not as impressed with that one. It is $100 less, though, so I will have to take that into account when writing the review. Still, if it were a choice between the two, I would take the AAXA.
If you’re not convinced and want to take a look around before buying, just be careful when choosing your $300 or less projector. Check the manufacturer’s name against our database of manufacturers – I personally would only ever buy a projector from one of these companies, as I’m weary of electronics from off-brands exploding or something ridiculous like that.
