Ordered Vankyo Leisure 510 based on glowing reviews on Amazon. Didn't meet expectations, which are not high.
Projections too blurry on top/bottom of screen (approx 20% of viewable area). Brightness is not sufficient for with some ambience light. PC or PowerPoint projections text are not clearly legible (I know it's not built specifically for that purpose). Maybe it's good for viewing movies in a totally dark room (which is not my use case). Only advantage? Price. Perhaps, u get what u paid for.
