Query: great idea, not well executed

These racks are a great space saving idea. However, I have had mine up on the inside of a solid wood cabinet door for about a month and it keeps falling off (double faced tape stays on cabinet, plastic rack piece comes off). I would also recommend separating the individual racks so they arent in a strip of 4. If you are using slightly larger sized spice bottles the plastic will stretch out unevenly at the ends causing the bottles to fall out.
