Product review (1 stars): Negative review, poor customer service, and very disappointed.
If you live with pets, I recommend you look elsewhere for your laundry solution.

I don't write negative reviews, but I'm so disappointed in the service and the design of this machine.  We bought this machine for our small family (2) and small house.  Initially, the machine worked perfectly, but about six months after we bought it, it stopped drying.  A service call resulted in some replaced parts and the cleanout of the condensation chamber - a part of the machine that is not owner-accessible and requires disassembling the machine.  A month later, we needed another service call.  Then another. And another. About 10 service calls in 5 months.

I'd read that lint buildup on the gasket could cause a leak, and that drying times could be slow, but not that there were any problems with lint buildup in the condensation chamber.  Each time we got service, we heard the same story - there's lint buildup in the condensation chamber.  Sometimes it was clearly lint; sometimes it was a mix of fabric lint and cat hair.

We live with cats - not dozens or tens of cats, but three.  Nothing in the documentation or reviews I saw indicated pet hair caused a problem with this machine, but it does.  We asked for a replacement and were denied, because we aren't maintaining the machine properly (by living with cats!).  Dog hair, I was told, would cause the same or greater issue.  And that this problem with pet hair is a maintenance problem.

When the machine is working, it cleans our clothes beautifully.  But - whether our machine is just kinkier than others, or all LG ventless machines have the same problem - we are out the cost of the machine as well as the cost of a replacement.  LG could have kept us as customers - but they just lost our support.
