“I bought the 4 port feeder (after the birds shunned a feeder I had purchased elsewhere). Within a couple of hours the little birds were queuing! I filled it with the no-grow seed from this website and the birds love it. I then bought the 2-port feeder and I filled it with a mix of berry suet pellets and mealworm suet pellets - and the birds love it. The birds are constantly using both feeders. I really recommend them. Easy to fill and clean too!”
