That's what I'm worried about! With rambunctious teenage boys that thing is definitely getting knocked in the pool! Was trying to figure out if there's a way to mount it up somewhere out of harms way. Let us know how the rear projector works!!It is right at the edge and very nerve racking with the little ones around. I think I was at 20 something ft. Its going back and I got a short throw rear projector on the way.
