very time consuming
The hardware included are for installation into a concrete ceiling. Well, I live in the states and do not have a concrete ceiling. So I went to the store to find proper hardware so I can mount it to my 2X4's/drywall. Installation time took a while for me. There's 14 holes I drilled for the 7 mounts which all had to be carefully measured out on the ceiling. After it was completed (several hours later) I tried it and was extremely pleased with the results.
