We now own 4 of these storage boxes. We bought 2 in 2017 & they've been outside in the Florida sun & salt air & hurricanes 24/7 since. No surprise that recently, because of my failure to provide regular WD40 maintenance on the boxes metal components (Struts/screws/hinges), the elements won the corrosion battle. We purchased 2 more boxes for replacement (they look good, are capacious &, despite our failure to maintain them, are extremely resistant to harsh weather conditions. In fact, the exteriors look as good as they did on day one. On a lark, we contacted the customer service folks at Lifetime & asked them if replacement parts (Hinges/struts) were available to purchase. They responded by sending out new replacement parts, at no charge, to us. This enabled us to salvage the existing boxes to a like new condition.  We highly recommend this product.
