My goal is to project PowerPoint presentations, PDF documents, Word, Excel, etc. as a presentation for customers. The projector must be small and light. He is also. Only with the projection ... that does not work on the internal memory unfortunately. This shortcoming is shown in the product description anywhere. If connected, the laptop via VGA, everything went fine. If you copy the same files on a SD card or in the internal memory of the projector, the projector can not display these file formats. This is very very bad. Since it was my goal to present gift without ion laptop without Ipad but directly from the projector, the device but can not this and this NON-Can, was nowhere read, I can only max. 2 stars awarded. If you want to play back images and movies from SD card or internal memory, the device makes sense.
