I bought 2 8x8 from Woot back in Feb, I love them, you have to be careful when using, Everything i read is donot pre heat in an oven.
I have a big ol 6 burner monster Thermadore cook top, need to slowly heat, 15 minutes low, 15 minutes med. then 15 high flame.
My wife said the burger I cooked her on this was the "Best" I have ever made.
Google Himalayan salt block and all kinds of Vid's
If your a serious cook, ya gotta try these.
Just noticed these are 4x8 kinda small
