Summary: i bought it to make my presentation-kit light-weight just connected it to my phone and displayed the presentation no cables to carry no heavy projectors and computers etc.... just my phone, 1 cable, and this picoprojector AND it's always in focus! BUT you need TOTAL BLACK DARKNESS for this to work.
Summary: I used this a few times to show outdoor movies after I purchased it at the end of October 2011. During the holidays I put it up for a couple of months due to cold weather and a busy schedule. I got it out last month to see that I was getting a red flashing light when I turned it on. I bought an additional battery thinking that the old one had just died due to "sitting" for awhile. That didn't work either.
Summary: I want to chime in given the overly optimistic reviews listed for this product. We've had the device for a couple of weeks now and I want to point out a few things that haven't been mentioned by other reviewers. The image quality is good given the size of the device and the brightness set to its highest value is sufficient.
Summary: This has the cool factor with a trio of lasers and single scanning mirror, but there are pros and cons, most significantly poor video quality. The most significant advantage is that the image is always in focus, even on uneven surfaces. The flip side of this is that because the overall picture diverges greater than the laser beams, when the picture is large, the spaces between the scan lines is annoyingly visible.
Summary: portable and easy to take with, however the room must really dark in order to see well. was meant to use in a classroom as a source sheet, but i couldnt use it bc there are no shades on the windows- oh well.
Summary: took a lot of time trying to decide which one is better.. ended up buying both .. ya i know.. ShowWX..Brightness: 4/5, Color 5/5, picture quality 2/5 PK301..Brightness: 3/5, Color 4/5, picture quality 5/5 ------ what i liked most about the ShowWX: smaller size, can recharge from USB, better battery life, no focus required what i didnt like: no flash memory (can only play off of a source), no VGA, need to buy the add-on which takes away the size advantage, is not good for...
