Pocket projector 3M MPro 120
I bought the 3M MPRO 120 Pocket Projector to use in my graduate seminars and I must say I am delighted with the results. I was warned that the image might lack strength and clarity, especially in larger rooms. But since I teach most of my seminars in windowless rooms to groups of only 6-12 students, too much ambient light hasn't been an issue nor has lack of clarity at longer distances. It's absolutely perfect for small classes like mine. The projector connects flawlessly to both my MacBook Pro and my tiny Eee PC Netbook without extra software or undo hassles. It's essentially "plug & play." I use it primarily for PowerPoint and videos, and haven't encountered any difficulties whatsoever. Sure, the image isn't as powerful as a full-sized LCD projector. But for quick and easy set ups in a small, dark room, it's perfectly fine. About the only thing I miss is a tilt or image keystone correction function. It's not always practical to place the projector at exactly the same height as the screen, so the image is inevitably distorted into a trapezoidal shape. It's not a terribly important issue ultimately--my students don't seem to mind. But it would be a nice feature to add on future models. The fan isn't overly noisy, especially when compared to full-sized LCD portables I've used. It's very fast to set up and take down. And because of the LED lamp, it doesn't get unbearably hot. All in all, I'm perfectly pleased with it. Sure beats hauling around the old 10 lbs. LCD projector I used to use. And in most instances, it's more trustworthy than the built-in computers and projectors in many of my school's classrooms. (Most have been mishandled, mis-wired, and improperly maintained. They invariably take longer to fix than it takes to set-up and run the MPRO 120.)
