Have owned the w/d pair for two months, other than the dryer making an occasional odd noise, they work wonderfully.  I put a new metal roof on my home, and removed the roof dryer vent. I was worried I made the wrong decision to go with a ventless dryer, but I took the leap of faith. The units work great, no complaints at all. Since I am now a believer, I have ordered the ventless wash tower. I hope they work as well as these do. The wash tower is 120v vs the 240v on this model. Will review once I get and can compare to the smaller pair.  I will put the smaller pair in my cottage. I am replacing an older bosh ventless that was not a heat pump, and it did not work very well. It would fill the room with humidity something these do not do supprisinly. I hope this review helps, there are no issues with drying at all...
