I have bought 2 of these ovens. 1 for the trailer and 1 for the house. With both of them the recipe books are missing. They will send you a pdf file but cannot send the physical book. Weird. My new one has issues though as it warms up it pops continually. This one will be going back as the ninja people said it isn't normal. I love the product but wish it wasn't missing the recipe book.
