I owned the previous Breville presser cooker. This is by far the easiest pressures cooker I have ever used. 
1st thing i made was Pork short. Ribs
I added 1/2 bottle of Waltons BBQ sauce ( no caliries, no sugar, no fat sauce. Then I added 1 bottle of ale and Cajun seasoning. In 40 minutes it separated from the bone. Tender and sweet. 
Too easy, excellent product!
