Projector is nice and bright. Simple to use and setup. Sound is fine for a medium size room, but also easy to connect to speakers. Overall a great value for low cost.
The only con I have found so far is while playing some video games. Games that require almost no lag (think rocket League) do not play well on this.
Also note that, to mount this, it uses just one hole (think of like a camera that screws into a tripod. So get the proper hardware if hanging upside down from the ceiling.
