This product did not stand up at all.  If you have a city location where it won't be tested in any form or fashion then it would work great, but if you have any other experience, this product will probably not work well for you.  We started by building it as described and it worked fairly well for about a week and then the birds started getting out.  So, we wrapped the entire bottom with cattle panels and then weighted it down with barrels.  This worked well until the frame around the door snapped one day and now it is completely useless as we don't have a functioning door.  It wasn't as if this occurred after having it set up for 3 months.  And because the pieces are snap together, there just isn't a good way to fix it now without replacing the whole thing.
