We have an ususual space under our sink and looked hard to find a unit that would fit. Very pleased with our choice. The pull out metal base is sturdy and well made and we like the fact that it is a platform as opposed to open slats. It was easy to install the unit. Just be sure to measure carefully. 
The only thing that might be improved is the lid handles. To minimize the height of the unit the lids are recessed and the handle extends only to the height of the sides. It is not easy to grip. Other reviews have suggested an additional knob of some kind could be fashioned and we are considering this possibility. Or, since the bins are small, we may just leave the lid off the garbage bin since it will likely be emptied every other day.
