Product review (2 stars): Not the best customer service or quality control.
I've had one of these units for about a year.  It does seem to get the clothes as clean as they get using detergent.  The first one they sent flashed red and I had to send it back to them before they would send a replacement.  The second one now has a fan running continually and according to the folks at Pure Wash, the unit needs to be returned.  I asked them to send me a new unit and let me return the old one in that box but they tell me I will have to return it at my expense in any appropriate box before they will send me a new unit.  This means we will be without the unit for a month or more.  It doesn't take too many of these returns to eliminate any savings you might incur in laundry soap.
