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: 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 bought this projector and only used it a few times.the projector overheats after 10 minutes and shuts down. i cannot use the product at all, no i see it cannot be returned? what kind of a customer service is that ?
Summary: We held high hopes for this projector, after heavily researching the mini-projector market and trying several other projectors--so much so that we ordered two units. It held the promise of a compact size paired with 300 lumens, USB plug-n-play, auto-keystone, and a reputable brand. It was perfect in every way except for the fact that both units overheated and shut off after 20 minutes. We were never able to get either projector to work for more than 20 minutes at a time.
Summary: I own two Optoma video projectors and they are great, but this one was did not perform well at all. First off the unit would shut off saying it was over heating after only 20 minutes. Another time it played and played with no over-heating. Than another time it would shut off after only 10 minutes. I returned this item for a refund.
Summary: Bought this to use with my Macbook Air. The USB display is not compatible with Macs. All over the outside of the packaging Optoma advertises the USB display but they don't tell you it doesn't work with Macs. They only reveal this golden tidbit of information until you have bought the product, plugged it in, pulled your hair out in frustration, read through the manual and notice in size 5 font the disclaimer that says "USB display is not Mac compatible.
Summary: On unboxing, I realised that in order to connect this projector to any HDMI source, a special (i.e. Mini-HDMI) cable is required: This is not included. What is included is a VGA cable (so old that I'm not even certain that modern PC's/Laptops have a VGA out socket anymore), and a USB cable (the one thing that you probably actually do have lying around as a spare at home).
