Since I was tired of my garbage in different buckets and anything but to dispose of space-saving, I have decided for this model by Franke. It is easy to assemble (with 4 screws) and disappears behind the wonderful kitchen cabinet door. more expensive models no longer offer in principle.
It also has the nice side effect, because unfortunately my dog is very greedy and rude, and it even if it is with yourself in cabinet doors open, so no longer comes to the trash and can be operated there.
