Summary: This 4 month old projector suddenly turns off the lamp after 5 minutes. Have called Optoma to ZERO avail. They apparently don't list it on their website either. First Amazon item that failed to deliver.
Summary: Better than expected able to display presentations in lighted room without difficulty. Little slow of a response with the remote but ability to view office files (from usb/internal memory/or micro sd card), pdf, images, movies and ability to convert to wifi easily.
Summary: Hi, I bought the ML300 Mobile Projector by the amazon in July 2013 and started using in August of the same year. The device worked very well the first three times. After that, when we try to use it to watch a movie, it comes out a message indicating overheating few minutes after using it.
Summary: I was scared reading reviews mostly about overheating problem, but I haven't had this issue with mine ML300. On the other hand There is a lot of issues with SD card reading and this stuff is very very noisy.
