Summary: I wanted to use this with a computer but found out that the brightness is too low unless room is totally blacked out and resolution makes anything but a PowerPoint slide with big letters unreadable.
Summary: It's not very bright. I did request a return from seller. He refused. I have no use for an image not as good as my lab top monitor. Would never be useful for meeting, but maybe okay for boys scouts to show movie in a tent for 4 people on a camp out. 3M Pocket Projector MPRO120
Summary: The pocket projector looked great on paper, but when it arrived here,we were very disappointed. We struggled to get the projected image to get much bigger than a CD case when the reviews said it would go up to 50 inches.
Summary: Flush $300 clams down the tube! From the outset I was disappointed with the projector. I expected it to be able to at least project a 30" image in a dimly lit room. With ANY light in the room you will be hard pressed to do better than a 20" image on a white wall or board.
Summary: This little projector needs to be taken back to the drawing board for updating and fixing. It's a great size, a nice price, but for displaying PowerPoint, pictures or dvd's,(isn't that its purpose?) it just doesn't cut it at all.
Summary: I bought this little pocket projector to use with my laptop to bring up spreadsheets etc. during meetings in my office. It was so pathetic, I have returned it -- poor projection quality; tiny image; dim; poor focus. What a disappointment!
Conclusion: O produto não é realmente da 3M. Comprei um do vendedor Novidades.2 (cuja descrição dizia que era um Mpro120 da 3M original e na caixa), mas se tratava de um piratão - um PP0033 Pocket Projector, que nem é da 3M. E no anúncio tinha um video da 3M e tudo mais.
