We needed an efficient, stackable, ventless, dryer for our small home. We have been using this one for more than a month and it meets our needs. Because it is ventless it does give off a significant amount of heat. Nice in the winter, but we may have an issue in the summer. The dryer does sometimes shut off, indicating that it has sensed the load is finished drying, and that is not always the case. we regard that as a minor issue.
