Product review (5 stars): No More Dishwashing by Hand.  Great Little Dishwasher!
Although I purchased the SPT SD-2224DS Countertop Dishwasher from another seller I feel that my experience with this unit might help influence others who are thinking of purchasing a countertop unit.
First, setting up this dishwasher is so easy a child can do it.  Basically, if you can attach a garden hose to a faucet you can set up this dishwasher.  From unpacking to ready to wash was less than 10 minutes.  (Suggestion:  Use plumbers tape on the fittings as an extra precaution against leaking)
I loaded the dishwasher up with some fairly dirty dishes and placed a Cascade Platinum detergent pad in the dispenser.  It takes about an hour and a half for the cycle to complete but it's worth the wait.  The dishes and silverware came out shining.  The results for every load since have been the same.
This unit fits perfectly on my kitchen counter under my cabinets.  It is very quiet (so quiet, my dog jumps every time it drains).  Perfect for an apartment or Tiny House.  My recommendation is to purchase an SPT Countertop Dishwasher.
