This product has been significantly improved over my prior feeder that was purchased in 2012. The pros are as follows:
1. Larger capacity - can hold 2 cups of liquid.
2. The wider and flatter base makes the feeder more stable when you flip the feeder upright once filled.
3. Wider opening to pour in hummingbird sugar water with less spillage.
4. The metal clamp folds completely over the top so it stands flat and is MUCH easier to hang since the handle is longer than my prior model.
5. The feeder top securely snaps onto the rubber bottom which prevents leakage.
Cleaning is still a snap - simply soak in hot sudsy water weekly. The only suggestion I would have made to the manufacture would have been to include a 5th flower on the feeder base as the wider design could have easily accommodated another flower and I think aesthetically, it would have looked even more attractive.
Overall, I love the modifications over my prior feeder and again, it is sooooo pretty. My prior feeder is 4-years old and still works fine so I expect the same from this product . The glass feeders also look so much nicer than any of the plastic feeders and although they are a bit more expensive, the price difference is really modest and worth every penny (right now, I think the price for this feeder is around $22). Lastly, you could use the glass as a flower vase during off season since it sits completely flat when the metal handle is rotated to the side.
I have no complaints with this product aside from the fact that my mother might try to steal it to replace her own hummingbird feeder!
