Product review (2 stars): For the cost, it should last longer.......
Installed it in November of 2012 and now it doesn't work at all.  Over the last 3 or 4 months, it got to where you could turn it on but couldn't turn it off and had to wait for the 20 second time out and it would shut off on its' own.  Now, it won't do anything.  Like others have said, it works great.......for a while.  It is expensive to fix it when it quits working.  Not happy.
