About 10 years ago i bought a similar product by „John Louis“. I really liked it. I found wayfair carries this Brand so i chose to get another same brand organizer for my newest home. 
The quality is still there, some changes in design. I preferred the rails from the first unit I purchased over the newer style. The original rail was chrome and I could slide the hangers along the entire rail. The newer system has wood spacers along the rail, which won’t allow the hangers to slide by. 
Installation is very doable, however, I would recommend that the installer has some skill working with their hands, carpentry, metal or whatever. Or have a helper. This shouldn’t be your first project.
Be aware too, that „SHIPPING“ is not included everywhere, unlike many popular retailers.
