Bought this after returning an Epson projector (due to awful connectivity). This unit has good picture (although 300 lumens a bit low), and good sound (although better when connected to UE Boom). Wireless Connectivity was miles better than Epson - but still poor. Airplay and Mirroring from iPhone doesn't really work (Maybe Casting with Android better?) To send signals from iPhone requires a special iPhone adapter ($52 extra) and HDMI cord. Then very good. Laptop the same - really only corded will work properly. Built in software is very clunky and local Apps much the same. Difficult to adjust screen size 16:9, wide etc. to suit. ...view more
