Wow! Awesome customer experience. Your unit was shipped. Except that there actually wasn’t any unit to ship…
For what it’s worth, I initially received a stinky unit, too. My customer service experience was very different though: my unit was replaced promptly and unbureaucratically.
If your Anova smells like mine did, it is unusable. I would insist on getting a replacement, no matter what stories you are being served about a stock shortage. (I don’t know what consumer law in your country is like. In Australia, where I live, I’m legally entitled to a replacement or refund. Which of these options is my choice, not the seller’s.)
