FYI, AC Infinity is offering free upgrades to all V1 fan owners. You just need the serial number and the order number. I bought 2 at two different times from Amazon last year, through AC Infinity's shop, and they replaced both. My serial numbers were even worn off from the tent and it wasn't an issue. When I submitted for replacement they said it would take up to 6 weeks but I got them both in about 4 days.
Also you don't have to send back the originals.
Here's a link to the form:
