While this unit is quite expensive, because it's very efficient and saves on space, we believe its worth the cost. We just installed it in one of our rental units that our child is living in. Of course, being a stacked unit, you would think its capacity is greatly reduced, but it's not. There's just a small reduction in the amount of clothes it will hold. Only thing we've found we can't wash in it are quilts bigger than twin size. Energy Efficiency The slightly smaller size means that it uses a lot less water than other units (our water bill has already gone down by 10%). So even though a few extra loads have to be done to compensate for the smaller size, it still is energy efficient. Cleaning Time It has normal cycles and the time isn't any different from full sized units. Performance Cleans just as well as a full sized unit. We've not had any complaints. Ease of Use Super simple. Easy directions. Easy choices to set your wash cycles. No problems. Easily visible and easy to reach. Design Same as other models we saw in the store. Durability We hope they last 8-15 years with normal wear and tear.
