This projector works great; easy set up, clear picture, simple controls, and even easy keystone adjustment. The one thing I didn’t expect was to hear it. If you’re getting it for powerpoint presentations, it may be a little loud. I use it for videos so the volume of the video overpowers the projector, but I was disappointed because I do also use it in a small classroom setting where it would be nice if I couldn’t hear it. I don’t know Dbs, but it’s louder than I had hoped. The Decibals weren’t listed in the specs. That would’ve been nice.
