Lifetime for plastic parts, all the metal parts will corrode or rust very quickly. I bought this lifetime composter after my last one last several years and no replacement products offered. This was the new and improved version of the one I had and it's been nothing but junk since the get go. The metal locking mechanism started to show since of corrosion very earlier on. The bell crank and arms have not seized up and you can not move the handle. The product should come with a plastic tube through the middle and stainless hardware they should also design it so you can fit a wheelbarrow.
