How to return my V1 MMM?

[VintageMA]

So - I'm not sure I am 100% clear on the return process for working V1 MMMs. I have 2 that are currently going strong and fan still works but I am still concerned about it dying on me one day.

Once the supply of V2 MMMs is good will we be able to replace the V1 that are working for free? I don't mind paying shipping, but I wouldn't expect to be asked to pay a replacement fee.
