Only used a few times and still learning the many functionalities it has except for the LG App the integrity of which remain unclear to me to this date. 
The machine is effective and efficient. Has a lot of functionalities that can be tailored to suit your needs. The only two loads I just did came out very nice and clean. So far so good. Oh, and it is very quiet, you can hardly hear it working even in an open room so that is a huge plus.
