With the Optoma ML1050ST, you can give presentations at any desired location. This mini projector weighs only 420 grams. This makes it easy to take it to a classroom or a friend's house. It's not a problem if there's little space, because you place the short throw projector close to the wall. This way, you prevent people from walking through your projection and casting a shadow on the screen. Thanks to the integrated media player, the projector displays files from a USB flash drive or microSD card. This is useful if you don't feel like taking a computer with you.
