Time to install : 1h tool require : drill + bit -lrb- for mount hole -rrb- , metric hex key ease of installation : medium -lrb- read the manual make all the difference -rrb- satisfaction with final installation : high I buy this mount to ceiling mount my Viewsonic Cine1000 DLP projector and find this kit to be perfect . I have a low , sloping ceiling with expose beam in my entertainment\/multi-media room , so the 6-axis adjustability , couple with the low profile , really help to turn the projector from a obstruction to a asset ! a couple of note from my installation experience : 1 . plan out you installation before start - this will save you oodles of time and prevent you from install and then re-installing 2 . dry-fit the projector to the mount bracket before mount it to the ceiling to make sure that it will hold you projector the way you want it 3 . have a friend help when you need to mount the projector to the ceiling bracket - it will make alignment much faster 4 . think about how the wire be go to run to the projector once you be do so you can incorporate the right length of conduit side note - I be a engineer , so I do not get frustrate with all of the adjustment and mount hole as some other reviewer do ... instead it be a wonderful little puzzle to do . however , I can see how people could get frustrated , so dry fit the assembly first : -rrb-
