Summary: Lots of reviews here knock this unit for many reasons and while they may be valid to a degree, with a little creativity they are surmountable. First, I did not purchase my MP220 through Amazon but through a selloff from another site where I paid $130 for the unit (don't ask where, they don't have them I won't use Amazon's reviews to stump for another retailer.
Nice little unit - ridiculous that all accessories disappeared off the face of the planet, but...

Summary: I purchased this due to it's decent price. I did not realize the unit was discontinued when I got it, so shame on me for not researching first. I read on the side of the box that only a USB cable was included, and for a projector to not include even the most basic cable to connect it to something I find a poor move on 3M's part. So once I took a look at it, it was time to go online and get the accessories I wanted.
Summary: The projector met and exceeded every expectation I had in terms of power and portability. My sole disappointment is that a remote is no longer available. You must manually operate the projector. This causes shake and decreases effectiveness of "instructor mobility.
Good unit. Hard to find cables to connect it to a laptop.

Summary: This is a good little projector that does everything it says it will do. The problem is that it requires a cable with a 3M proprietary end to connect it to a laptop, and unfortunately, that cable is no longer available. It took a bit of shopping and experimenting to find a work around for the projector, but it is possible.
Summary: Mostly I am very happy with this. Buying the remote is critical if doing a presentation. Also, the images in folders seem to get sorted by date only (unless someone knows away to change this) which means to get them in the order I want, I have to arrange the images before hand (by changing names to alphabetize them) and then running it through some batch conversion software (I use Graphic Converter) which takes the alphabetized images and converts them in that order,...
Summary: The MP 220 is includes an impressive set of features. It is amazingly compact and lightweight, especially considering its outstanding brightness. The combination of being capable of running on batteries, plus having its own Android operating system and internal memory, enables you to use it without any cable connected to it - which is really a great advantage. The drawbacks of this projector have to do with its bundled software.
