I've had this feeder for a couple of months now, and although it got off to a slow start, once my birds discovered it, it's been a big hit. I use shelled peanuts, and I've constantly got 5-8 finch, nuthatch, or sparrows feeding at once. I even saw a ladder-backed woodpecker on it yesterday. I initially tried it with a baffle, but the birds didn't take to it and the wind kept knocking it out of the tree. It's easy to fill, but the only thing that could be improved is that in order to keep the product inside fresh, you need to empty it, estimate how much is needed to fill it, and then pour the old product back in on top of the new. If you let it run low, the birds don't have enough space to all eat at once. Overall, though, a good product that attracts the right birds.
