US = OP300 vs UK = OP300UK
The Ninja Foodi has been available in the US for some months longer than in the UK. It is my understanding that its availability in the UK is rather recent.

There are a few difference between the US OP300 & UK’s OP300UK version. Notably Temp is Centigrade – most recipes I have seen are listed in Fahrenheit owners guide – and the interface reflects that.

The other potentially confusing thing I noticed in a quick stare & compare was the use of the term Grill in the UK – The US models use “Broil”

It may be (but I do not know) that the included recipe book may have been edited to Brit/Metric terminology – giving quanity in grams instead of ounces – perhaps you can confirm that for this inquiring mind.

Since it is a OP300 version, the Dehydrate function is not offered.
It also seems that the “unique to Ninja Foodi Accessories” are not yet offered in the UK as yet

Although “rumor has it” that Shark/ninja will be offering several on Amazon in both the US and the UK sometime soon (today is April 2019)

Many, if not most of the accessories we discuss are often found on Amazon so that is one place my Brit friends have been successful in finding useful pots, pans etc. MANY of the accessories for Corsori, Instant Pot and many Air Fryers can be used in the Foodi – just watch the height carefully. Foodi’s pot is slighter wider and not as tall (based on manufacturer’s published specifications.
