Summary: Bought this to hold daily meetings for my projects. So basically I have to show some static content that is easy to read (Excells, ppt., Jira, etc). I have to say it is good for that, and you DO have to close the blinds in a room to get a comfortable picture. Do not mistake this for a full powered projector, it is only comfortable for meetings within 1 hour range, any more than that and it is uncomfortable for your eyes.
Summary: I use this projector for business meetings when the conference room is not available. Plugs right into my windows 8 laptop launches and I'm ready to go. I don't usually carry the power plug with me and the USB 3 plug provides the juice to get a reasonable image brightness on a off-white wall. (Real World results) You don't have to keep a battery charged which is nice and makes the unit light weight.
Summary: We purchased this projector to use in meetings (Powerpoint) while travelling. If you use both the USB power cord and the AC adapter power source, the projector is bright enough to be visible in even well-lit situations. If it would allow zooming functions, I would give this 5-stars.
Summary: Remember when purchasing that you get what you pay. I have owned this for over a year now, and while it is does not offer what a $2K projector would, it is sufficient in every way. I have used this on the fly to give PowerPoint's, did a display of an electronic book that was purchased, and set it up on my laptop for the kids to watch a movie using this.
Summary: Excellent product, very reliable, and light. I was surprised by the image quality even in partially lighted rooms. Of course i`m able to bring with me in the same pc case. It would be better with an HDMI port, power swicht and a longer usb wires (not so hard they're to rigid) I do really recomend for sales and executives professionals.
Summary: Pros: Price Very light and portable Simple to use Bright for the price Cons: Can only use with A PC Not as many features as more expensive projectors The C-120 is exactly as I expected. Very simple to use - just attach to your PC. Everything else is plug and play. At a meeting I used the C120 with a group of 6 people in a dimmed - but not dark - room. The image was not at all bright until I remembered to use the external power source.
