Product review (3 stars): It failed in less than a month
It is nice that it comes with the bracket so that installation is fairly easy and all you have to do is to
remove the dryer vent and it is readily accessible.  The downside is that 23 days after I installed it
the part failed.  Amazon is taking it back.  I have the ability of changing the part myself, however I
feel for those who have to call in a repair technician and get charged $50-$75.
It gets a "3" rating because of the no hassle return and I feel my time is worth something.
