I have played with several of the Bosch, Asko, Eurotech, etc., as they tend to end up in condos that have no way to vent to the outside. They do seem to work well considering, but the customer must follow the recommended maintenance to keep it working in tip top shape. But I think the biggest expectation that must be set is they dry sloooooowly. If the customer expects to use it just like the dryers they had in the past, they will never be happy with the performance. But if you don't have any other option, they do what they were designed to do.
