I read the reviews before buying this unit. Being cost effective is what caught my attention. If I'd known the instructions were this horrible I probably would have purchased it. The mfg. should be ashamed of themselves with the dark copy so called instructions that were included not to mention the CD included also, did not work. Thank goodness for YouTube otherwise it will still be sitting in the box for a few more months. The threads barely fit some parts of the unit. All tools are not included, as you will need a small Allan key also, and possibly a small rachet wrench as the one included is universal. I have yet to use it but, hopefully I won't have difficulty with registration of the screens. I know you get what you pay for but, it doesn't xost the company much to insert good instructions. I will be mounting it on a a Heavy Duty workstation purchased from Harbor Frights and adding casters to the bottom to roll to a corner when not in use.
