buy this to mount my Epson 8350 projector ... I be die to get this thing mount and in my living room . however , it be not to be . it `` just miss '' the hole on the 8350 ... some people in the review have say it do fit the Epson 8350 and it have detail instruction . the product I receive do not fit it , and it be `` instruction '' be one sheet of paper let you know how many of each piece you should have , and a schematic . no step by step . regardless , call the return phone number on the packaging , and speak with a woman who say , in addition to the 1 '' and 3 '' extender that be include , they also have 5 '' extender , which would fit the Espon 8350 . they be ship `` for free '' -lrb- with a $ 3 shipping charge -rrb- . so , although it say UNIVERSAL , it be not quite . I 'll update my review when the piece come in ... but I now have to delay hang this a week . I would rather not ... sigh . = = = = = update = = = = = i receive the extender ... and it work fine . but it be false advertising to say this be `` Universal '' when it do not fit all projector . so ... buyer beware .
