Works well, the springs hold the screen plate tight and the plastic body is thick and strong. Installation was easy, with a head screw on the lid to hold it against the mesh wiring of their rabbit enclosure. One star deduction for the price. It's not that big and consists of two pieces of plastic and base metal that are attached to each other. Under 10β¬ I would give 5 stars, but for 15β¬ it's not a good price. The thing is high quality but expensive because of the materials used.
