I have used this Perky-Pet hummingbird feeder style for years, it is the best one on the market. The hummingbirds like the perch and in the spring we have to put out 2 of these as we have well over 30+ hummers flocking to the feeders. We put one on each side of the house as the little hummers are very agressive. These feeders are so popular at our home that we have to fill them every day in the spring for a few weeks. We keep one up through the winter as we always have a few that seem to stay. When the food is frozen we bring it in for an hour or so and defrost the food and they are ready for the sweet little hummers. Someone comented that they are hard to clean, well maybe but I just take an old bottle brush and bend it a little and it works just fine on the bottom part and the little flowers pop out and I clean them with an old tooth brush. You can also buy more of the flowers. My only complaint would be that the perch after awhile (1-2 years) gets a little brittle and if you are not careful unscrewing the base the perch may break. Also we have a couple of Oreols that love the sweet food and so I take out a flower so they have a bigger hole to suck up the food. I will always by this type of feeder as long as they make them!
