Broke,
The system works fairly well, but I live in earthquake country (here in the People's Republik of California). For a while, I thought this idea of hanging sharp tools over my head might not be such a good idea for that reason. As it turned out, when the last big quake hit in 1994, the stuff in the shop hanging on a hook and the cabinets on wheels were the only things not to get dislodged, smashed, and over turned. They just moved as they needed to and stayed put.
