assembly instruction be not quite clear , and some piece be very difficult to put together , especially after thread the cable through the shaft high up by the ceiling . also , my hdmus cable be heavily shield , and do not thread easily through the shaft . get my rg6 and power cord through be also tough . I be happy with it now that it be up , but it would be better if the finish product be more rigid . another complaint be that they provide 4 and 5mm bolt to attach the mount , but mine need 6mm , so off to Home Depot . off again to Home Depot for a second trip , as the lag screw they provide to thread into the ceiling joist be make of metal so soft a phillip head screwdriver will strip they . I get they most of the way in before they strip , then have to use a pair of vice-grip to take they out . I get some stainless steel one and install they with a socket wrench . overall a decent product for the price , but they should not provide screw as soft as ju-ju-bee .
