PERFECT
We love these birdhouses so much that I'm writing even before I'm asked!  Because we've had other bluebird houses in the past, we knew what to look for and I feel so fortunate to find these on Amazon.  They are perfect in every way.  They even have the exact needed screws already screwed into the top of the base just enough so that you are ready to continue screwing into your surface.  Another plus is that they are made so that you can easily clean them out when needed.  The price is fair and the construction is excellent!
