Bought this on a recommendation from a bro in law as a cheaper version of a Bosch.
On a scale of 1-10 I would give it an 8 3/4 - 9.
It is very quiet. It has a 2 motor design that allows top rack washing only - more efficient than most. It has convection drying - keeps all the moisture inside the stainless tub.
The only reason I would not give it a 10 was it was a bit harder to install than US brands as the rear level legs are non accessible from the front - necessitating one to slip the unit out from under the counter a few times to get it level - not a biggie. On the other hand the fill and drain are all at the back - makes it easy to check for leaks out from under the counter completely - while running.
The unit is fully enclosed with painted metal sides and back covering the insulation. If someone put a butcher block top on it, it could be a free standing unit - with proper precautions, of course - to make sure it did not tip over with the door open.
The top rack - initially was a disappointment as there no real vertical tines to hold stuff secure as the older Whirlpool I replaced had. It was just getting used to the way it loads, and now it is fine - if not actually better. The plastic parts inside may be suspect in a couple of areas. The tube that brings water to the middle spray arm (under the top rack) came apart a couple of times due to it sticking a bit at the back rubber inlet seal. It is easily replaceable, and I will eventually do so - but for now I just attached a black plastic tie to secure it better, and it is fine. (I may not even worry about replacing it) :).
Overall a quiet unit, well made & efficient. I bought mine from Buy.com and it came on time and undamaged (due to excellent packaging by Haier).
A great option at a lot less money than a Bosch.
