once install , it be quite adjustable and will do the job adequately for the price . however , get to that point can be difficult . if you be someone who insist on read the direction instead of just try combination you feel be intuitive , you be likely in for a struggle . when you open the instruction , you be go to wonder how such a seemingly simple device can possibly have so many part . the various explode view may send you reel . however if you just like to start fiddle and see what `` work , '' you might be ok . there be several logistic landmine you will have to overcome during this product 's installation , and the asian-influenced text be not go to help thing . good luck try to install the `` tube nut '' -- unless you be on a ladder such that the ceiling mount be directly at eye-level , it can not be do , and there will be a lot of grumble . also , this product may not work with certain projector that have only three thread mount hole -lrb- as oppose to four -rrb- , especially if they be close together . I get it to work on my 3-holed unit -lrb- optoma ep726 -rrb- , but the configuration I employ to get there be pretty insane . in sum : good if you want to save money ; not so good if you do not have about 3 hour and a lot of patience .
