I was absolutely impressed with this system! I did a lot of measuring and had to use a tape measure, drill, level, metal hacksaw, rubber mallet and stud finder. This can not be completed without your own tools. Once the measuring and drilling is complete the process is super quick and easy! Be aware that the instructions tell you to space out the shelving that will be fixed, but keep in mind, there are only actually 4 shelves - so plan in advance if you want even spacing of your shelves. The Stow company was wonderful and we had a few pieces arrive broken but, a quick call to the manufacturer and they sent me replacements without any trouble. Overall, I am extremely satisfied with the result and I feel very confident that my closet system is sturdy and will hold the weight of my clothes and shoes.
