It was making a whistling sound in different places when we first blew it up.  The blower is not that strong or because of the leaks the moon bounce was not very sturdy, the sides kept coming down. We purchased this slide based on age recommendations being for 10 and 11 years old.  It is the perfect size for children up to age 6.  There is stitching hanging out in several places.  I was surprised because of the great reviews written on this website.  We paid for expedited shipping and insurance.  Sending this back immediately.
