i am very happy with this bird feeder.  It is replacing a round one that was not too sturdy and that squirrels were getting into and dropping all the food from it.  I love the fact that it is made of recycled materials and that it can be easily  filled by lifting the top.  We have several kinds of birds coming to feed and lots of cardenals who are always around. The mesh bottom is wonderful because the food does not get mushy even when it rains. It is lightweight and sized perfect.  We use mixed seeds since we have different varieties of birds that come to feed. The covers on the sides are good to prevent birds from getting inside.  This is a nice bird house that we are really enjoying and recommend to everyone looking for one.
