Product review (4 stars): If you want clean clothes
We bought two of these washer/dryer combos, one from Amazon and one from Home Depot. The delivery from Home Depot was late,  Amazon was right on time. We use one at our home and the other is at our vacation home.

A normal size load takes about 3 hours and usually comes out a little damp, but dries after sitting in a clothes basket for about 10 minutes. Small loads come out much dryer and usually take a little over 2 hours.

The reason we wanted a ventless dryer was because clothes out of a normal dryer come out smelling dusty. You see, most dryers pull air off of the floor of your laundry room and blow that air through your clothes for about 45 minutes. Often laundry rooms are not the cleanest room in the house. Ventless dryers do not pull in dirty air, they heat up and dehumidify the air in a closed loop inside your dryer. Clothes come out smelling much cleaner, although a little damp sometimes.

There are other advantages to this combo besides not needing a vent. It uses half the space since you only need one unit to wash and dry with, it plugs in to a normal 120 volt outlet, no need for dedicated 30 amp dryer outlet and of course there is no need to remember to come back later to switch the clothes from the washer to the dryer. This way if I put a load in right before I go to bed or leave the house they are done when I get up or return home, so in some ways it can actually save time.

The reason for only 4 stars is that on both units we own, the drain pump broke after about 6 months, so I would recommend buying an extended warranty. In both cases LG was out within 2 days to fix it at no charge. A price I am willing to pay for cleaner, dust free clothes.
