The installation was very easy and the perches are sturdy. We were at first disappointed when we took them out of the box as the leaves just looked fake and poorly placed BUT once we put them on the wall and arranged the leaves they were literally perfect. The leaves have wiring so they can be reconfigured which was a nice touch and for the price these are fairly unbeatable. Our cats go into total hunter mode up on these which is quite funny but we take a feather toy and they go crazy jumping between them and hiding in the leaves.
