Product review (1 stars): It's a great idea, but the actual unit does not work
It's a great idea, but the actual unit does not work!  We installed it, and it appeared to work correctly for maybe 10 loads of laundry.  When it stopped working, we returned it and received a replacement unit.  We did this within the 60 day warranty period.

We installed the second unit.  IT DID NOT WORK!  NOT EVEN ONE LOAD!  We immediately called the company, and requested not a replacement but a refund of our money.  By this time, however, we were outside of their 60 day warranty period.  After several phone calls, they absolutely refuse to refund our money but will only send another replacement.

BUYER BEWARE!  It's still a great idea, but this company is not producing a quality product; and when it fails, you're the one who's out the money.
