Pretty Good Especially When Price is Down
We have several chicken houses that we inherited so from time to time we have to replace this. It’s a pretty good deal. They work well and seem to last so far.

Was a perfect fit for the one that stopped working. Be sure to follow directions to purge any trapped air after you install it.
