I've had one of these feeders for over 3 years now and it's still working fine. I've read other reviews that say it broke quickly and I'd have to attribute it to putting the feeder in the sun.  I had a different type of hummingbird feeder that I hung at an east facing window and it began to crack after one summer and failed after less than 2 years.  Sunshine will break down any plastic feeder quickly, causing it to crack and eventually fail. Direct sunlight will also cause your sugar water to spoil faster so you have to change it more often.  Find a northern exposure window or place it under a shady awning or eve and it will last for many years.  If you want a feeder in a sunny window, you'd better stick with a glass model.
