3M MPro110 Projector: Pros

Posted on July 11, 2009 by Art Feierman
  • Extremely portable, smaller than a pack of cigarettes ("100's"), definitely "fits in a pocket"
  • Simple to use, essentially plug and play
  • Composite video input
  • VGA input - so far, this is the first pico sized projector to offer one, and it performs reasonably well
  • Battery good for about one hour of use between charges
  • Relatively quick recharge (4 hours or less)
  • Built in recessed screw thread for a standard tripod screw
  • Good resolution for the class - 640x480, which you can appreciate, especially through the VGA input
  • Long life LED light source, rated 20,000 hours - by the time you get through 20,000 hours (20 hours a week, for 20 years), you'll long since have replaced it with newer devices

3M MPro110 Projector: Cons

  • Colors tend to be oversaturated, gamma high (dark image), and too blue. Skin tones are dark
  • No image controls
  • Very limited brightness - suitable only for small screen viewing - maximum size is about 48 inches diagonal. Even if you want to go a bit larger, it won't focus for a larger image size than that
  • Overall a little less functional (inputs, focus, etc.) than some others in its size class
  • No speaker at all - if you want sound, you'll need to come up with a solution elsewhere
  • If you want more playing time, you can buy an optional spare battery, but to change them out, requires removing a small screw - a minor nuisance

3M MPro110 Projector: Typical Capabilities (for this type of projector)

  • Fixed lens - no zoom
  • Brightness - at 8.8 lumens, the MPro isn't as bright as the Optoma, but but a slight bit brighter than the Aiptek
  • Documentation - not bad, but typically "thin" on details
  • Warranty - 90 days parts and labor - average, but some offer 1 year
  • Phsyical size
  • Weight
