So after going around town for a few months, I discovered that my options for a vertical freezer was Haier or Haier. So we got the Haier.

Before I spend the next week researching what temperature to set the freezer to, I would ask for the collective wisdom.

My colleague sets it to -18C so I've done that. I know trucks with chicken will throw out all chicken if temp goes above -13C.

Somewhere in between the 2? Any particular reason (other than power), eg better food condition?
