Poor lid design By Jim

Squirrels having a field day. Top pops right off. No locking mechanism or slotting on the top to lock it on at all. Birds having difficulty using but having patience.

Response From Perky-Pet®
Jennifer : Consumer Relations Representative

We are sorry to hear the squirrels were able to gain access to the seed through the lid of the feeder. To deter the squirrels, we recommend adding cayenne pepper to the seed. It will not affect the birds since they have no sense of smell or taste, but it will repel the squirrels. Also, we recommend placing the feeder at least ten feet away from launching spots (such as trees or decks) and at least five feet above the ground.

Please feel free to contact our Consumer Relations Team at 1-855-PERKYPET (1-855-737-5973) with any questions or for additional assistance.

Needs a locking top By bruce

2 days, and our squirrels figured out how to pop the top off and climb down inside the tube and help themselves.

Patty : Consumer Relations Representative

We apologize for this experience and would like the opportunity to learn more.  

This feeder includes a twist lock lid that should prevent squirrels from accessing seed from the top. Please give our Consumer Relations Team a call at 1-855-PERKYPET (1-855-737-5973) for further assistance.  Our feeders are covered by a one year replacement warranty.

Squirrels love it! By anon

This is my second one and the same thing happened to it as to the first one. It lasts under two years, the inner tube cracks down the seam, the squirrels chew through the plastic on the bottom holes. If it weren't for the squirrels this probably would have lasted longer and would be a nice bird feeder as the birds love it when the squirrels aren't hanging off it. But like a previous reviewer wrote, they jump on it, hang upside down and eat away.

Response From Perky-Pet®
Patty : Consumer Relations Representative

We appreciate the time taken to provide this feedback and apologize for the experience.  

The metal cage is designed to prevent damage to the feeder from squirrels.  Additional measures can be taken to keep squirrels away. We recommend placing feeders at least 5 feet above the ground and 10 feet from the nearest jumping-off point, such as trees or decks. Adding cayenne pepper or safflower seed to the mix will turn squirrels away.

Our feeders are covered by a one year replacement warranty. Feel free to contact our Consumer Relations Team at 1-855-PERKYPET (1-855-737-5973) with any additional questions.

goldfinches By Howie

I ordered 2 of these feeders following an invasion of American Goldfinches and it was the best thing I had done. These feeders hold a super amount of sunflower hearts and I had enough seed to maintain this large flock of 45 goldfinches and House Finches. I highly recommend this easy to fill feeder and above all it is easy to clean.

Poorly made product By tinkin

I ordered two of these, and both of the plastic containers inside were cracked and broken. The packaging was horrible - nothing protecting either one of them side by side. So had to wait a week for two replacements plastic containers, and they were packaged better, but I noticed lined cracks in both of them. I didn't bother calling to have new ones sent. The metal is fine, but the plastic container is poorly made. Will not order anymore of these, and was very disappointed in the product.

Easy to use By Bobbi
Love so far! Holds plenty of feed and easy to fill. Lots of openings so many birds can access at once. Took the birds a couple days to learn to use but now it's getting plenty of use!

Quality By pcs901
This is my second Fortress Feeder. The first one lasted 10 years until a windstorm knocked it off the branch from which it was hanging. This one looks like it will last at least as long.

Holds lots of sunflower seeds By Haikuman
The birds love it and the squirrels quickly learned to leave it alone.
Nothing available for them.
