Product review (5 stars): If it were legal to marry an appliance, I'd treat this washer/dryer combo so fine.
My partner and I LOVE this appliance.  I wanted something to streamline the laundry issue because I really, really, really, really hate doing laundry.  I hate it.  So, when I saw this unit as a viable option as an eco-friendly, money-saving, and time-saving alternative, I knew it had to be mine.  There was a bit of a learning curve, but it wasn't the machine's fault as much as it was my limited knowledge for using it properly.

-Clean the door gaskets once a week.  I just use a kitchen towel and my finger to really get up in there and remove lint build-up.
-Check your filter at the bottom twice a month, especially if you have pets.  Keeping this clean will ensure the water is draining and your clothes are drying.
-Use the proper settings.  If you're washing a comforter (Yes, it's that big!), make sure you have your washer set for the correct load capacity, and the dryer option set for "More Dry".  By doing this, your unit will run super efficiently.
-If your clothes feel slightly damp after taking them out of the dry, flick them in the air once or twice and, voila, the thin layer of moisture just evaporated.  Done.  Dry.
-Don't overload it.  In fact, don't overload any washer or dryer.  Your clothes will come out wrinkly, wet, and not as clean as you'd expect.
-Accept that it's going to take an extra hour for a load of laundry to be done.  You're not using a vented heating element.  The trade-off is, your laundry won't go all mildew and funk on you because you're a human being and you forget things like laundry sitting in the wash from 4 days ago.

A little maintenance with the lint trap and rubber door gasket (I'd say about 10 minutes a month) is asking so little to have more space, a lower energy bill, 1-step laundry completion, and a unit that literally sings to you when your laundry is done.
