Negatives:
- The pull-out frame is adjustable only in certain stages, that is engaged to about a centimeter in the next stage one. This means that it is not suitable for all furnace! For me it is either too narrow, so that it falls out of the track, or too wide, so the slightly recessed metal feet on the oven-rails. The baking tray tilts so at minimum contact and then hang at an angle in the oven (on a page with the actual pusher, on the other side with the metal feet).
For me it is therefore absolutely not be used!
- The pull-out can be badly adjusted (even if it must be so adjusted only once, provided there is an appropriate level).
- Should there baking sheet without the use pull-out (they are detachable) have to be careful, because the edges of the sheet can be very sharp from below.
- My copy had a damaged (chipped coating) on the back in a corner.
All in all I can not recommend it because it is not suitable for an "adjustable" baking tray for all oven sizes, and therefore you have to order on Good-luck the sheet. In my case it was not right and is right back to Amazon.
