The Birds Choice Medium Hopper Feeder was design with durability in mind. I love that this product is made in the US and from 95% recycled plastic. The feeder is mainrenance free, easy to fill and the mesh screen base allows for seed to stay dry and smaller particles to fall through and not build up over time. In a few minutes, I has this feeder filled and put in place. I recommend this for its durable build, maintenance free design and ease of fill. Highly satisfied.
