This feeder is made with very high quality ingredients.  The sides and top are made out of recycled plastic.  The bottom is a mesh screen that allows water to drain out, but keeps the seeds in.  The sides are at least 1 inch high which helps keep the seeds from blowing out.  The roof is movable so it makes cleaning easier. The opening is big enough for larger birds.  I'm so happy with this feeder.   I can see this lasting a long time.
