Bests & Worsts Reviews from Amazon

I just bought these from costco at a better deal but they are definitely quality! I did a comparison with my old sheets... Side by side in the oven and used storebought cookie dough (kind that comes in little portioned squares). The cookies on my old sheet started burning on the bottom so I took them out a few minutes earlier than the nordicware. The nordicware cooked the cookie perfectly. they came out rounder and did not start burning on the bottom like the ones on my old sheet.
