has replaced a 6 year old AEG top device with us, is much more processed-quality and better, VA (Plastic rollers etc.) and quieter in viiiiel wear parts. Would not the light indicator on the bottom, you did not know that the device is working! However, 1 star deduction due to the lack of interior lighting and the very complicated instructions for door installation, which consists of only tens of interlocking drawings, without text!
