Summary: I was excited about the possibilities of this projector - I thought I could use it to project movies, slides, etc. from my computer. Wrong! It's just not bright enough even in a dark room. In addition, the colors fade noticeably the farther you project the image. It may be fine for sales presentations in a small area, but for what I would use it for, it's no substitute for a large, bright lamp projector.
Summary: If you are considering the 3M MPRO110, my recommendation is that you fully understand your use and purpose as well as the limited capabilities of this product before you buy it. It is definitely NOT a replacement for the typical portable projector by any measure. It certainly looks impressive and is a very compact unit. It will suit the specific needs of some but generally does not compare well with the capabilities of other portable projectors.
