I have a small one that is years old. I fill it every 3rd day and get up to 8 birds on it at once!!! I purchased the larger one for my son recently but felt it was too big. 3 lbs is a LOT of Safflower seed! So we exchanged it for the smaller one and we both love it and get tons of birds. It helps to use an aluminum pan to sit it in while filling, then dump the seed that fell out and into the pan back into my pouring container.
