Projector planet behaved perfectly with this order. The projector ceiling mount seems like a great bit of kit, and it fits my optoma hd26 projector with a bit of fiddling about, and swapping the mounting arms for the smaller included extension arms. But customers should be aware that the fixings required to attach the mount to the actual ceiling are not included. Nor is any advice as to the size or number of fixings required given in the instructions. It would have been better if fixings had been included in the kit, as I now have to work out which ones to get to safely support this heavy piece of kit and go and buy some screws. For the want of about 2 pounds worth of screws I'm annoyed and frustrated with it, instead of being delighted!
