I have been using this for a month now.  Excellent easy to understand and use features.  It is located in the garage so the cycle complete notification feature is very nice.  The only problem was installation and initial operation.  An error code was displayed upon delivery which was missed.  It was discovered to be an exhaust airflow blockage.  The outside flappers were clogged which was fixed but the error code does not go away for several cycles.  Initially I contacted support which scheduled an installation revisit but it was cancelled when I resolved the problem.  Yes, I had to read the manual, but it would have been nice if the technicians at LG new about the error codes and delay in clearing.  Would have saved time on both ends.
