This is a very solid bird box which should last years with proper maintenance. The slate roof is not only particularly attractive feature, setting this box apart from many others, but also a practical roof materiel which will keep the rain out, keep the tenants insulated and prolong the life of the box. In short, a quality product at a great price. I cannot fault the supplier either, their price is always very competitive if not the cheapest, and more importantly my orders have all safely arrived within 48hours, having been well packaged and placed in the responsibility of a reliable courier who kept me updated on the estimated delivery all the way to my door.
