I just purchased a new home and installed one of these shelving sets in each of the three bedrooms. The first one took about an hour to install with two people. By the time I was on the third one, it took less than 30 minutes. These shelves effectively doubled my storage space in each closet. The only negative is that the toggle bolts that are provided (for use in parts of the wall that don't have a stud) were useless. Better off buying some nice drywall anchors at a hardware store if you come to that. For the price, these closets can't be beat.
