Ah OK, slightly different version to the showwx. Uses DLP projection instead of raster scanning. Performance is still roughly the same, maybe just a smidge duller due to the DLP chip. Then again, DLP projection is usually not as harsh on the eyes in terms of flickering.
Just a warning, if you have a laptop or something with a bodgy power supply (Ie, it'll zap you if you are touching ground), then don't use this projector while it's plugged into the wall, or you'll fry it. Some strange reason they don't include any kind of protection against that.
