Product review (4 stars): Good for small space, 2-3 people, where time is not an issue

Even the inside pockets of jeans in a full load are dry. We didn't change anything, and it performed as described below for over a year the same way every time. I don't know what happened, honestly. I'll update this review again if something changes, or provide details on how to fix a drying issue if I can ever figure out what happened.

I poked around the washer and realized that my drain pipe was higher than the washer recommends. The washer recommends that the hose positioned at the same level as the unit or below. Fortunately I had another drain option and repositioned the drain from the higher one to the lower one. Performance is still good on drying.

Regarding the issue of drying, which I think is the most important piece of deciding whether or not to purchase the unit, the short version in my case is that most fabrics that are washed and then dried need to be placed on a drying rack. I'll detail my complete experience below.

My situation is simple. I live with my fiancee and a small dog in a small condo where the only option for a washer and dryer would have been this combined unit or the specialized Bosch washer/dryer units for small spaces. I work in an office and my fiancee works on a farm with horses. All of our clothes always come out clean, and we have not had any technical issues with the unit.

Washing -
This machine is a proficient washer. There are more modes and settings than most people will probably need, but for everything I've put in there (jeans, t-shirts, dish towels, regular towels, sheets, light blankets) the basic setting works well. Items that the dog has soiled with urine are cleaned by adding specific cleaners on top of the regular dosing of detergent.

I always wash clothes with the cold water temperature setting as I don't feel it is necessary to wash clothes with warm or hot water, although those options are available to you if you want them. I don't use detergent designed for cold washing, just unscented Arm and Hammer, but if you are concerned about it I believe companies have produced detergents with enzymes designed to activate at lower temperatures. The unit uses water efficiently as it continually sprays clothes with jets of water, tumbles, and repeats until the cycle has finished. This differs from conventional top-load washers where the basin is filled with water and your clothes are rotated in that water.

The system has some bright lights to illuminate the drum even if you have no other light source.

Drying-
This unit is certainly not a powerful dryer, and drying will take a few hours. The more you fill the drum the longer it will take to dry. There are some fabrics, mostly polyester I think, that will actually come out dry enough to put away. However, things that are made with thick cotton will need to be dried on a rack. The articles that come out the most damp for me are underwear and socks. Jeans and towels come out reasonably dry, but will still need a few hours on a rack. Given that most clothes need to be dried on a rack, you won't be able to get the dryer soft feel.

Drying comes as a bonus, as I would otherwise have no options for a dryer in my condo, so although it does not perform as well as a regular unit, I think its acceptable.

I haven't tried to get clothes to come out of the unit wrinkle-free, but there seem to be settings to achieve that.

Other considerations-
The unit performs what I expect it to do, but there are a few other factors that I feel are important to mention.

There can be an issue of mold growing in your unit if you close the door after use and do not clean the rubber that seals the door. However, if you purchase the unit you will notice that the door, much like a car door, has two positions, part-way open and full-open. If you slowly close the door from full-open you will feel it come to rest in a position with a small space left for air to pass. This is enough for the drum to dry out between uses, which solves the problem of mold growth. Watch the uploaded video for a demonstration of this.

The unit has a nice feel to it. The buttons are solid, the moving parts lock into place, and it rewards you with nice chimes when you turn it on, change a setting, set it to run, and when it turns off. It's absolutely silly, but the ending song is actually pleasant to hear. I actually find myself looking forward to hearing it. LG seems to have adopted this musical feature in their appliances and I think its a good decision that shows they are thinking about the details of design as well as the big picture.
