Another error I frequently made in the beginning was when the timer went off, I checked the food and decided to give it more time, I used to forget to push the temperature button again (just presumed it would continue as previously set but no, it doesn't). So be careful here too.
Especially when you have heaps of ingredients in the and then you notice in the recipe you're trying to convert that it says grate the chocolate or parmesan. Something you should have done first when you're using the TMX.
But then if you have money to spare; why not.
