This has been a nice addition to our kitchen, the waste bins are large, stuurdy,  and maximize the space of the cupboard. The unit was easy to assemble and install for us, there are four screws that hold the sliding mechanism to the floor of the cabinet, the only part that took any thought was making sure the frame was straight in the space. The slides move easily and quietly. The handle on the front isn't overly useful because it always falls down, but still works, and the bins do fit snugly in the frame which is nice for keeping them together, but can be annoying if you have overloaded the bins and are trying to get them out without spilling because they will catch on each other. Overall though, it is a nicely constructed setup with insignificant downsides.
