Summary: Bought the project for occasional use. Used it one time and the next time I pulled it out of the box it wouldn't work. I sent it back to ViewSonic and it took them well beyond the promised turn around time for repairs. They sent a refurbished model at that and not the original. I used it once and it worked fine and now it doesn't work again. I have had it less than a year and have less than 2 hours of use.
