we have 4 of these deploy in a bar environment switch on 12 + hour a day to show sport and other tv channel and we could not be happier . they be exceptionally easy to install with a simple menu that make it easy to invert the picture , adjust the keystone setting , and basically set up the projector so that the only button that need to be press be on\/off . fortunately , there be a remote so there be no need to touch anything on the unit itself . in we case , the bulb last 6-8 month each and be also easy to change . I test one at home where we be lucky enough to have a very , very large white wall and watch Avatar . Short of cook up some popcorn , it be like sit in a movie theater . it be true that the project image lack the definition of a average high-def flat-screen , but the image size be significantly larger than anything you could reasonably buy as a tv . for watch movie and sport , what this unit be capable of produce be truly remarkable . while I be sure there be many better projector in term of picture quality , none come close at this price point . I would highly recommend for anywhere you need a big screen .
