I bought one of these houses five years ago. I have built and bought martin house for over forty years and this one is the worst one I have ever tried to use. First the perches keep falling off. I had to tap the plastic and put a washer and screw on each post before they would stay on. The clean out bottoms will fall open for no reason. I installed the pole head pipe in concrete and the pole worked pretty good for a couple of years. I removed it every season and made a cover for the head pipe opening. The third year it was all I could do to to get the first pole into the ground mount. At the end of the season, I had to use a pipe wrench and a piece of pipe to try to get the lower pipe out of the ground by pulling up as I walked around in circles. It would not come out. So now I have the first section of pole sticking up in my yard all year. I had to rivet the bottom clean out section just to keep it together. The plastic piece that holds each section up in place broke and now the house is unusable without those 2 special pieces. There was always gaps between the sections when it was on the pole. I think that is enough to change your mind.
