Update, Wayfair was not as excellent. Apparently having loose parts rattling inside counts as "item not as expected" instead of defective so you get charged over $30 for return shipping. 

Wayfair was excellent. The GE was NOT ultraquiet. It rumbles and rattles. Kept me awake. Note that it is heavy and longer than a usual window unit. It was hard to get into and out of the window opening. Tried two different windows and various foam pieces to get it to quiet dhow to no avail. Returned.
