Educators please note: Expect BenQ, like most manufacturers to offer better than their standard warranty when volume school purchases come into play.
Consider BenQ's overall warranty to be overall competitive. Ultimately, this should prove to be a low cost of operation projector, thanks to the 3 years, and the lightsource potential of 20,000 hours!
Other than that, I have been impressed with BenQ's overall support, over the years. On the home theater projector side of BenQ there were a couple of issues, with certain models - one recent, one 4-5 years ago. In both cases, BenQ's response I considered to be first class.
