I wont try and order anything from Junk-USA1Industries (Based on numerous customer complaints on platforms like
Yelp, the Better Business Bureau, and Facebook, USA1 Industries has a pattern of severe shipping delays (sometimes over a year), poor customer service, and difficulty in obtaining refunds. While some customers praise the quality of their interior parts, many cite issues with backordered items and lack of communication. )
