We got a round stone for a wedding present and didn’t use it for probably a year or two. Once I started using I realized how great it was. Now I use it all the time. I just made biscuits on it the other day. I do think a square one would be nice because I could fit more of my non-pizza things on it. and especially my Naan pizzas, which are smaller and I never seem to have enough room to fit them all on. The stones get hotter than hot and a millisecond of touching it will hurt for quite a while.
