Review on 🍪 PERLLI Nonstick Bakeware Set - 10 Piece Baking Pan Cookie Sheet Set | Lightweight Kitchen Convection Oven Safe Pans | Baking Trays Bakeware Sets | Healthy PTFE PFOA Free Non-stick Coating | Up to 450°F by Kristen Simon

TLDR; Leaves warp and don't retain their structure, which can lead to unexpected clutter and safety issues. I wouldn't recommend buying the bakeware set which had a great variety of pans and the reviews were pretty good. (I never write bad reviews, but when I bought a few things moving into my first apartment, I ordered a few things to fill my house and kitchen). I will be simple and precise. Pros: Excellent non-stick coating and easy to clean. Cons: The baking trays are very deformed. Roast chicken at 425F. The plates (both large and small shallow pans) were there, and as the cooking progressed they began to warp more and more. It got to the point where the buckling caused the corners to be at about a 15 degree angle and all the juice started moving to the undersides, causing me to have to constantly remove the drain pans. Of course, that's far from ideal when the baked goods have to be mostly in place and come back at any time. After cleaning, they've tightened up a bit (probably from cooling), and the angle of the blades is adjusted slightly, but still stays in place. at an angle as shown. I would not recommend them. Sometimes it's okay if they aren't perfect, but I don't want anyone wanting to bake and not expecting distortion that ends up making a huge mess and creating safety or hazard issues. I used a cake pan. Time. There's no warping, likely due to the stronger construction due to the lack of a wider, flatter, open face and narrower edges. This did not warp (however used on 350F, not 425F). Still usable until I get new ones, which will be very soon.
