You can read the original post here.
It was only after I wrote that post that I thought "hey, what if there was a lifetime warranty on that pot?", because you never know about these things, right? So I had emailed the Lagostina company, and they got back to me right away saying that there was in fact a lifetime warranty and that we should send them the pot for inspection.
So on Tuesday September 21st, Ruth put it in a box, and sent it off to the Canadian Lagostina office outside of Montreal. It cost $9.32 in postage to mail the pot. It was just sent general mail, not any kind of express service or anything.
Today, only two weeks after my original post, we received a brand new pot from Lagostina! It came with a note saying that they sent us an improved version of the pot, because the original one was discontinued!
So, hats off to the Lagostina company! What GREAT customer service!
