Product review (5 stars): It does the job right and saves money
I bought an used one and used it about 10 times a month. After 3 years, it still works like new.
I tested with a Kill-a-watt and found it costs about 0.13 KWH to run a full cycle which means the cost is less then $0.02 per cycle. It also doesn't need lots of detergent.
