This was for my 94 year old mother who is on the 2nd floor of an assisted living building.  She missed her birds from her house.  She is loving this!  Took a while for the birds to find it, but now they are there everyday.  The other residents and staff love it as well.  Would give it five stars, but the plexiglass does get dirty (like a windshield) and is difficult to keep clean.
