The capacity of the tanks (20l and 10l) is ideal when you are 2. A bit tight for a family of 3 or 4 people. The guides are flexible and seem robust. The large aperture provides full access to both ferries, handy when to empty or remove trays. The cover swings back and can be easily removed for cleaning. Hardware provided to secure the bin to the furniture.
It lacks just a little mechanism for automatic closure of the drawer when pushed, but good ... I quibble! Excellent product!
