We bought initial pieces of the system years ago but never got it installed.  I finally did the job this summer.  Easy to install the rails but I agree the holes could be spaced a bit better to hit the center of the studs.  Covers went on quickly.  Hooks were super easy to hang and I could quickly change locations to achieve the best organization.  Really cleaned up the space and made everything more accessible.  So pleased, I'm going to buy some shelf units and some wall pieces and hooks to finish the job completely.
