The media could not be loaded. UPDATE (with photos) 7/2016: I've been using these pans for years and I just wanted to update this review by saying that I'm still using these, with no spray, and all I do is wipe them off when done using them. They are the perfect size for filling an oven with one tray. They hold a ton of cookies and still look BRAND NEW from buying them years ago. See my most recent photos of me taking cookies off of the pan with EASE! Love these pans! Original review: These are by far my favorite baking sheets for flat-surface baking (I have another brand I prefer when I want sides on my pan so that my items don't go flying anywhere). I have purchased the AirBake brand as well and I do not like them as much. They are not as heavy in weight and the metal is not as good quality. My cookies bake superior on these pans. I have had two for over 5 years and I use them in a commercial kitchen. Unfortunately I started using spray on them so they've lost a bit of their original character, but, overall, they're still going strong. I just added two more to my collection to help with pan rotation as my cookies are getting more popular. Pros: These are nice a large. As you can see from my photo, this pan nearly fills the entire rack of my standard sized oven. I make extra-large cookies at the coffee shop (2 tbsp of dough) and I can fit 3 rows of three comfortably. If you were making normal sized cookies, I'm sure you could fit 12-20, depending on your size and spreadability. These pans DO NOT NEED SPRAY. Fight the urge to spray them, I beg you. It'll ruin the finish over time. Furthermore, they really are non-stick. I can bake cookies on these and take them off and the pan doesn't even look like I used it. These pans are nice and heavy, which in my opinion is necessary to get the correct heat transferred around your baked good. The double-layered bottom allows hot air to flow beneath the surface of your cookie, almost simulating a convection oven style of baking. These last. As I've said before, I've had two of these for over 5 years and they're still doing the job for me. I recommend them to everyone! The lip is great for pulling the pans out without burning your hands or touching the cookies. Unfortunately, if you're a pan rotater, you may have difficulty since the lip is only on one side. Because these pans are pretty much flat with no sides, they store away nicely, I have mine nesting next to each other and can slide them in next to where I store my cutting boards. If you do work in an industrial kitchen, these do fit on sheet pan racks fine, though they are smaller in dimension than a full sheet pan, yet, larger in dimension than a half-sheet. Cons: Because of the air stream technology of the double-walled bottom, there are holes in the bottom of the pan. Should you have to wash this (really, if you don't do anything crazy on them, you should be able to just wipe them off with a damp cloth), be careful of putting the entire pan in the sink. If you do, water will go into that bottom layer. Not a problem, but, you'll want to be mindful that when you lift the pan out of the water, you'll have a stream of water coming out of the holes. Keep the pan at an angle and let all this water empty out before storing. I had issues with ordering these off of Amazon and them arriving bent or dented. Make sure you inspect yours when they arrive. Amazon has excellent customer service, so, don't let a bent pan get you bent out of shape :-) I had one that just a corner was bent and I was able to hammer it back into place no problem. When these are brand new, they are SO non-stick that your cookie dough may actually go flying when putting dough in the oven (I especially noticed this with snickerdoodles as they have that sugary coating all over them). Just make sure your cookies are still in place once you get them into the oven.
