By default ovens are known to come with very little equipment. 1 grill and 1 baking tray was the case for my Samsung convection oven. I find it a bit poor. Since I bake like just lacked a correspondingly deep baking tray. In Accessories Samsung none was to be found so I decided to order THIS baking sheet, since it corresponded approximately to the dimensions of my oven. This was finally arrived immediately unpacked and tried. Perfect fit and without jerking or squeeze fits this baking sheet perfectly into the rails of my oven. On the Roll extract these unfortunately do not fit. This I can but get over. After the first cleaning of the baking tray, it was immediately taken "in operation". At 180 degrees and almost 2 hours baking time the baking sheet absolutely still in the delivery state. States: No warping or buckling of the material. Furthermore, nothing has remained stuck to the plate. The cleaning was also without problems. My impression after one use is very positive and the price fully justified. I would recommend this product to other buyers only! Should over time result in changes, I will pass on this course. Therefore: Have fun and especially long "Back and roasting" pleasure with this product
