If your unit is defective, there are free returns for the first 60 days after you order, and a refund (if you order through anova, this is not the case for 3rd party sellers, or other outlets). There is also a one-year warranty in the case an issue comes up later.
The first 60 is free shipping, and afterwards, the same is true for the warranty, but there is not the refund option, just a replacement.
I live in Thailand, I asked my friend to bought an APC and take it back to Thailand with her ( she is coming back to Thailand the end of this month). I just look up the warranty policy, Thailand is not in the shipping list. So if my APC has a problem what can I do?
