It's not the brightest projector, but decent image quality for one-on-one presentations or very small groups, coupled with lots of features and a reasonable price, has most experts pointing to the 3M MPro150 as a solid choice among pico projectors. Small enough and light enough (at just 4 ounces) to fit into a big shirt pocket, the LED light source can project a 20-inch image under normal lighting conditions, or up to a 40-inch one if the lights are turned low, despite the paltry 15-lumen brightness rating.
Among the pluses is the ability to read and display lots of different file types, including PDF files, Microsoft Office files, and most common video, graphics and photo file formats without the need of a connected laptop. When a laptop is called for, Wi-Fi lets you make the connection wirelessly -- a good thing because cable drag makes the MPro150 susceptible to toppling over. Files can be downloaded from your laptop and stored in the 1 GB of internal memory, or loaded via the USB port or MicroSD memory card slot.
Among pico projectors, the Optoma PK301 (*Est. $380) scores somewhat better reviews overall, but it also costs more If you need something just a little bigger and a little brighter, the BenQ Joybee GP1 (*Est. $380) is a micro-portable projector that weighs just a pound more, yet can display images up to 80 inches in dark rooms, or 60 inches when light levels are a little higher.
The 3M MPro150 earns a fair share of recommendations from reviewers. ProjectorCentral.com, PicoProjector-Info.com, and GadgetSpeak.com offer the best insights.
Reviewer Bill Livolsi gives a perfect score to the MPro150, recommending it as a business projector to be taken seriously. Despite a generally positive assessment, he complains that he must pay extra for 3M's Presentation Binder (*Est. $40) to provide storage and a convenient screen surface. His one serious caution is that the tiny projector has a sluggish menu.

Ron Mertens describes the MPro150 as the best pico projector his organization has yet tested. He goes on to compliment 3M for a big step forward by designing in ample internal memory and for accommodating a MicroSD card for extra storage. In a separate review, he compares the 3M MPro 150 favorably to the more-recent (and more-expensive) 3M MPro 180.

The 3M MPro150 earns GadgetSpeak.com's Highly Commended designation, receiving a rating of 4 out of 5 stars. Anonymous reviewer "petew" describes it as small marvel obviously targeted at corporate sales and business presenters. His main objection: The MPro150 can easily be knocked over when it's connected to a cable.
