I've had my composter for several years and have enjoyed it's efficient and easy performance.  The only complaint I have is quite similar to others listed ... the hinges and metal external parts rust and I've found no way (rust removal liquid, spray, etc.) to prevent it.  At this point only one barrel is functional as the other barrel's lid will not open.  The saving grace is that the customer service chat function was extremely easy to order replacement parts - I'm not thrilled with the cost of replacement parts but it's cheaper than replacing the barrels.  Lifetime needs to find a better protective surface for all exposed metal pieces as it is truly IMPOSSIBLE to prevent rust when being used outside.
