We purchased this to save room and electricity (compared to normal separate washer/dryer) We ran into common long dry times and found how to correct them from different sources on the internet.  We also currently have a leaking drain pump that is being replaced under warranty - started leaking about a month after install.
Wish LG website had better troubleshooting and common issue help.  Have to clean the condenser every couple wash/dry cycles, but there is a guard screwed on covered by sticker that has to be removed first.  Also the unit can wash a larger load than it can dry, so washing smaller loads work better or separating the washed cloths into multiple dryer loads.
Overall a good product so far, just different from normal washer/dryer pair.
