So far so good
Only had it set up for a short period, but so far so good.  Installation is fairly easy.  As others have noted, the template is incorrect.  I just cut the template in half and taped on a sheet of paper to correct the distance between the holes.  I added the lights to to outflow from the furnace.  On my unit, there is no location to mount bulbs to shine on the AC coil.  Didn't make sense to add the bulbs to the return air.  If the coils are contaminated, it would just contaminate the outflow air.
