Works well for the squirrels, though a lot of it ends up going to other animals too. Small birds slip in and grab some food, even though they've got their own feeders. Mice have no trouble helping themselves either, they just climb up and go right in.
Easy for the squirrel to open the hatch. Spacious seating area. It's easy to see when it needs refilling. Both the squirrels and the feeder are very happy with the feeding station.
