Bests & Worsts Reviews from Amazon

I purchased this bat house because I was about to evict a good number of bats from my attic. The fact that it was approved by the Organization for Bat Conservation was enough for me, and it's worked out well. I installed the bat house during the winter near where the bats were entering my attic. I then put up wire mesh to keep the bats out. When summer arrived, most of the bats moved into their new home. A few somehow found a way into the attic... oh well... it's much easier to clean up after a handful of bats rather than the 30 or so that used to live there. I've had this bat house for almost 3 years now, and it's held up well. The bats keep coming back so I guess they are happy with it too. 6/2013 update: On year 4 now and the bat house is still in great condition. The bats have returned and each year there seem to be more bats than the previous one.
