Why there are some holes on the surface of material？ Due to the large fabric of the product, some positioning holes are necessary. Needle holes are used to guide sewing and will not reduce or impact on the quality. Don't worry, this is not the fault of quality. Why is air out from seams? Is it normal? Bounce houses are made of sewing by hands, like our clothes. The air leakage from the seams between material is normal. Therefore, keep the blower working always, do not stop during inflating. Why does the blower sometimes stop during using? There is a controller of temperature when it meets the set, the blower will stop working and will continue when it is cold or down. This is not a quality issue.
