We bought this a month ago and it sounded strange at the beginning with a scraping sound but it was working. Two weeks later it was scraping itself apart. When repaired under warranty they found that the blower was incorrectly installed at the factory and was scraping the walls with a massive screeching sound.
As told to me this is not unusual for this product. Disappointing to see this happening to GE.
No, I do not recommend this product
