The unit is very sturdy. After reading the manual plug unit in and set controls. The unit is very quiet @ Medium. Nice sleek design. The controls on top is very handy. Another feature which is nice is when to empty the bucket. Just purchased today Sunday Aug. 15, 2021 see how it performs. I guess after 30 years it was time to replace. It was easy also to register the product. Time will only tell about the unit.
