This is at least third one we have purchased.  We've left them with all the houses we have sold.  This box holds enough cushions for 4 patio chairs, a carpet, two flag poles and flags.  Everything stays dry in the rain/snow.  We don't put a lock on the lid, but we do use a clip to make sure the lid does not blow open in strong winds.  We had one issue with the current box lid, but Lifetime replaced it.  We will continue to buy Lifetime products and particularly the outdoor storage boxes.
