Mira's cut. A ceramic pizza stone holds heat better than thin steel. It fits a 12-inch disc in your grill without warping.
I keep seeing thin steel discs warp on home grills, so I looked for a ceramic pizza stone that handles the heat. The goal is a 12-inch disc that stays flat and stable.
Check the product photo for a solid ceramic disc. Look for a 12-inch diameter and a thickness that suggests it will not flex under weight.
How Mira kills a phone accessory
I throw out any listing whose title does not name the phone. Then I keep a short set with a real listing photo.
- The Amazon title names this phone, not last year’s.
- Listing photo is from that product page.
- MagSafe / USB-C / bump cutout is in the title if the pick needs it.
- Public rating exists when Amazon shows one — not a fake lab score.
If the title is for a different generation, I would not open the box. Check live price on Amazon.
