Pros: Simple menu system. While portable it does support cieling and reverse mounting.
Cons: A bit noisie and early models didn't shut down long enough for everything to cool for long life.
The set-up was pretty easy and it does hang upside down from the ceiling with the greatest of ease. I can hear it if I listen for it and there is no or little sound in the room. I do expect my next projector to have a cleaner picture but that's some time away with two more bulbs to go through. I'm very satisfied with my $700 purchase and it's great to run the PC without glasses. Now if Windows 7 just had a great app like ControlAV2.
