Love the Convenience

I have had this for several weeks and love the way it works.

Beautiful machine does it all.

I really like this new machine. Washing and drying all in one compact place.

No delicate dry cycle

by: GandSinWP

No, I would not recommend this to a friend.

Source: lg appliances.com

As long-time users of an LG all-in-one LG was our first choice for replacing our 15-year-old unit. We are deeply disappointed. Our clothes consist of many delicate fabrics. While there is a delicate wash feature there is no delicate dry capability on this machine. We are looking at alternatives as LG would not do anything for us and has pushed this off on Home Depot.

All in one washer dryer

by: Gail Lee

Yes, I would recommend this to a friend.

I bought this a month ago and absolutely love it. I read s lot of reviews and watched a lot of U-tube videos before my purchase. I fell a lot of the negative reviews are operator error not the machine

Does not dry

by: Refinnej

No, I would not recommend this to a friend.

Source: lg appliances.com

I had to return this unit due to the fact that the unit does not dry. I am very disappointed with the marketing of this unit as well. When it was delivered it read washer on the side. Many of the loads take over 7 hours and the clothes are still wet. This unit is a huge disappointment.
