Having personally tried three micro projectors (the AAXA M1, AAXA M2, and Dell M109S), here is what I think of the M2:
Lightweight and pretty bright for a projector of this size
Competitive pricing for its class of projectors
Easy to setup
LED light source, meaning energy savings and less switching bulbs
More noisy than other projectors in its class
Wish the resolution could be higher
Menus could be easier to use
Having said the above, and even with the caveats of noisiness, etc., I would still recommend this product. This is because it is brighter than the other projectors I've tried (AAXA M1, and Dell M109S), and brightness is really important for micro projectors.
I would like to say that I've had a very positive experience with AAXA technical support. When I first bought the M2 projector, the projection colour was off, and the AC adapter failed. However, AAXA technical support responded quickly to my email about the malfunction and replaced my projector quickly. Now the system is working fine. The service I received was much better and courteous than others.
(1) There are pros and cons as indicated above and in the other reviews.
(2) My projector was defective at first, but
(3) AAXA technical support was responsive and very nice, gave a free replacement very quickly, and I am satisfied.
I hope these points will help other buyers to come to their own conclusions.
