I purchased a seed feeder which was supposed to prevent corvids and squirrels from getting to the seeds. The feeder arrived very promptly so I have nothing but praise for the company. I do have some reservations however about the design of the feeder. It does not prevent magpies from reaching the seed. I needed to fix rectangles of steel mesh on the outside frame opposite the feeding points to keep these corvids from reaching the seeds. I also had to bend and reverse the metal from which the feeder hangs in order to prevent squirrels from removing the lid. If anyone actually reads this perhaps it may result in a design change to allow future customers to improve the ratings.
