I purchased my trusty Lifetime Deck Box for use on our rooftop deck. As luck would have it, Chicago was weeks away from one of the toughest winters in years. While nearby lawn furniture collapsed and cracked and even portions of my neighbor's roof gave way, my Lifetime Deck Box took the worst that mother nature could dish out and shrugged it off like a champ... my tools, supplies and assorted nick nacks literally looked as if they'd been stored inside all season, while gale force winds, feet of snow and ice crystals were swirling overhead. An absolutely solid investment. Thanks
