UPDATED**Still feel like this is a great addition to our home and for the birds. We have blue jays that I feed with this and it is really fun to watch them interact with us and the feeder. One complaint is it is difficult to keep clean and sealed, otherwise excellent.
This is exactly what I was looking for. Easy to put together and the design is very efficient in holding the feeder together without any screws or nails. The only exception I would note is if you have a thirty inch or 32-inch window you will want to cut the two side bars shorter by about three inches, this enables the entrance to be wide enough as the picture shows it to be.
