Bought a couple Crisbee pucks last week, got to try it out on a Gris #9 DO lid, #5 Lodge 3-notch skillet, and #8 Gris LBL skillet. Although I didn't cook on any of the skillets yet, seems to work very well. Darkens up pretty good after 3 trips to the oven (per recommendations from Crisbee). Even the kitchen smells a little better.. :icon_thumbsup:
