Has replaced with us just a 3-year-old heat pump dryer. This was very noisy from the very beginning and at the end was unbearably loud. All the more we were surprised that may be quiet a dryer sooo. Further convincing speed and automatic control, which works well even for small quantities. Some parts are occasionally in Mixed filling not quite trrocken, but that's dear to us, as if the laundry "broken heating" is.
