If you (and this is key) FOLLOW THE DIRECTIONS, you'll have this pan a long time.

I have only used it 6 times and it has warped sufficiently that I have to "control" the skillet to prevent the batter running to the sides

I nearly cried the last time I used my old griddle.

I have used this on a glass cook top about 8 times and it has not yet warped

Not worth the money, only used 4 -5 times and it warped.

FIRST time we used them, I noticed horrendous scars on the bottom of the pans
