Why ?: The two stars there that I find it fascinating what to micro construction is possible today. There remain then but two stars because the projector in practice, that is to say as a work tool for professional presentations but also in the private sphere as a player and then is when it is not really suitable for a video. UNFORTUNATELY, I would have loved this little thing called my own, if it had fulfilled the requirements. But I will make it short: I threw PowerPoint presentations at night in the dark living room to the feinverputzte in clear and white living room wall. However, the device is really faint, that is only at absoulter darkness (as one reviewer already described) has a fundamentally recognizable image. In practice, that in "normal" meeting or conference rooms you not found before such a darkness. And the main shortcoming that has led me to return the next day: the lack of color. In professional: GRAPHICS business developments in various colors showed who were clearly distinguished with high quality projector or on the laptop are with this projector color indistinguishable and therefore worthless. Then I instance. Red marked fields of a table with black lettering it. Again, on the other display devices to recognize everything clearly. When mini-projector, however, the fields are unreadable, you see hardly that ever a font is in it. If the device so even for PowerPoint (which indeed now lives from its graphic / color properties) is suitable, it is not to be used. Last but not least the test with a film of DVD: Again, very weak, pale colors. A night scene around a campfire: the Minibeamer only the faces of the matter seated human recognizable, original and trees, rocks, etc. So even on business trips at the hotel I suppose it's better my Sony Vaio notebook "to bed" and watch on a decipher movie takes something bad recognizable on the Zimmerdecke- or wall to try. Would appreciate a tip if there is a mini device that does what it promises to you -or davon-.
