I love the design of these Squirrel Feeders, we have gone though multiple wooden feeders over the past 15 years due to chewing up the lids and boxes. Your design saves us
a lot of money by preventing the Blue Jays from stealing all of the squirrels peanuts. We feed the " Western Silver Gray Squirrels ", they are like having a circus outside our windows. We feed at least 8 squirrels that come daily and they eat close to 5 lbs. of peanuts a day. Peanuts can get expensive, so it has been an ongoing job trying to keep the blue jays and Crows from cleaning out the feeders. I purchased 3 of these feeders and mounted them on 3 separate trees. They still fight over the feeders but at least the feeders are no longer emptied by blue Jays. We put out sunflower seed and bird seed for the Quail, Doves, Blue Jays, Turkeys, etc... I will stay with these feeders, they are heavy duty/ indestructible.
