This is our 3rd portable dishwasher, the GE replaced a 15 year old Kenmore.  We’re very happy with how clean it gets the dishes, how quiet it is and that the dishes dry well when you open the door at the end of the cycle.  A couple of minor observations/concerns:  
1.  The hose doesn’t retract all of the way back into the unit - it sticks out a few inches.  It seems that the hose reel won’t spin back the entire way - perhaps the spring isn’t strong enough
2.  The cutlery rack is flimsy and doesn’t sit firmly in the bottom rack and the guide covers are more nuisance than useful - we removed them after about 5 uses.
So far, we’re pleased with the purchase.
