Absolutely LOVE these!    My husband had to remove a half shelf that was in the cabinet but installation of these was very easy.   They are high quality, work very well and once installed, are firmly and permanently in place.   I liked them so much, I've ordered two more for the cabinets in my island.   One note of mention - you do lose about an inch of width of storage space because the frame needs to be able to fit in through the cabinet opening but well worth the loss for the ease of drawer storage.   Another thing I should mention is that I was even able to use a wire rack on the top drawer to stack some of the items for efficient storage.   I definite 5 out of 5 stars from me.
