Bought the bamboo in drawer knife storage and I was surprised at how sturdy it was.  I bought two, since my Mother-In-Law has a lot of knives.  It fit the drawer perfectly with room to spare (30 inch wide drawer).  It allowed her to remove the knife block from her countertop giving her more room.  We had no issues with fitting her knives in the block.  She loves it!

Pros: Price was great. Quality.
