We were a bit concerned about the fragility of the lid but for now all is well: above all, never place anything on top, or allow a child to force the opening engine. The cover is very light car shall be opened by the small motor to solar energy.
One downside, the highly sensitive detector Opening: if you mettaez your broom or your water packs near the bin, it will open as soon as you frôlerez. Prepare him therefore a location in a specific area.
A button launches the aperture manually and to prolong the opening time until you press the "close" button which is handy if you have to pay something in installments (eg off plates).
