Purchased 2 systems for a new large walk-in closet in home reno project. Installation is complicated, but luckily I found a series of YouTube videos that show step-by-step what's needed. I would recommend that anyone watch the videos before installing, it makes the process so much easier to follow and gives you a few tricks that help you avoid potential problems with alignment. After installing the first system, the second system was a snap to cut and fit into place. With the parts I had left, there was enough shelving to fit out a small hall closet as well. They look great, are very solid, high quality and expensive looking. My contractor was impressed that I did it myself!
