Great product, only wish it came in more widths so I could put them in more cabinets. Pretty easy to install, hardest part is reaching inside the cabinet to install the screws so working on the lowest shelf in a base cabinet is the hardest. A paper template for drilling the screw holes would help immensely! They do take up space so you could stuff more stuff in the cabinets without these but have bought 5 now and now things stuffed in the back that you forgot you had are accessible.
