Needed a new set after my very expensive “lasts a lifetime” set failed after just 2 years. I have 5 other Ninja products and NONE of them have failed me threw the years, so thought it only made sense to purchase their pans! So far so good! Pans are awesome and the stackable lids are such a neat little bonus! I love these so much I’m going to purchase the bigger pan to add to it! Honestly can’t go wrong with Ninja!
