I am by far no stranger to kitchen duties but I am new to the MAKER brand of products. My wife and I retired the use of any aluminum cookware and any Teflon coated products many years ago due to the negative health issues with both. We use stainless steel, glass and ceramic and do not miss the others. Since my wife makes our bread from scratch (grinds wheat and such) we are always using the oven. These MAKER "cookie" sheets are perfect for making bread and tonight we'll be testing it on some salmon. Both sizes are perfect (large is 19.45" x 12.14" x 1.05" weighing 2.5 lbs, medium is 17.44" x 11.94" x.0.84" weighing 2.0 lbs) and the silicone handles help the oven mits to get a firm grip. I'm not saying the silicone handles don't work on their own but since I hate being burned I'm not taking any chances on touching the metal. The ceramtec coating allowed for the bread to slide right off. (CeramTec coating is also used in medical equipment and internal parts such as knee replacements but I'm not sure if it's the same product but it has the same name.) Cleanup was super easy and as you can see by the pictures there was no staining. There's a trough around the edge of both for catching runaway liquids.The price is excellent for two quality cookie sheets. Can you get sheets cheaper? Of course but they won't be good for your health and they'll warp in a very short time. I'm sold on this cookware and will definitely be looking into more of the MAKER brand.UPDATE:We've been using these pans a few times a week and up to this point were very happy with them. After a wonderful salmon dinner last night I noticed the larger of the two pans had warped badly. Over a half inch wobble from corner to corner is now obvious. I have some really inexpensive pans that have never done this. We stayed below the maximum heat rating and the fish only backed for 15 minutes. This is not good and I'm very disappointed. They seem like such high quality too. Now I have to remove my recommendation for this cookware.
