So far the birds in my garden have not used it! Perhaps because the other feeders are easier to use. I had hoped it would attract smaller birds while at the same time keeping the larger ones, e.g. magpies, at bay. Perhaps the holes are a little too small, although other purchasers have not raised this as a problem. Given more time the birds may yet use it.
It is smaller than the photograph seems to imply - even with the measurements given.
