Super happy with this very helpful shelf saver.  My existing shelving was bulging with too many items and desperately needed just a little more room.  I only had 5 1/2" of free space, and this sweet darling slid right in and plenty clearance under my kitchen-countertop.  I now lay my roll of paper towels on the top of canned vegetables and still clears the counterop.....saving room from them on top of my countertop...bam!
