The RollerFeeder has been tested and in the field (customer owned) since 1998. The test sites are located in the northern woods, suburbs, and city environments. In most cases, the feeder hangs directly from a tree limb or hanger without other squirrel deterrent devices (guards etc.). RollerFeeder has consistently prevented feeder problems such as rodent animals and birds i.e. Grey squirrels, Red squirrels, Raccoons, Starlings, Blackbirds, etc. RollerFeeder also has its own on-going test site with three feeders, they hang in the middle of a large pine tree with several branches nearby to make it easy for squirrels to launch from.
