I got these after seeing the publishers preview. They are exactly as described. These maps are just what I need to generate dungeons on the fly. They are not pretty, but they seem very functional. 20 different Caves & Caverns. A very detailed map key which instantly tells me how doors locked, where traps are located, and what monsters may be in the area. I like the white space for making my own notes. I will print one map for my players, and one for myself. For the price, these can't be beat. But they are probably not for everyone. Still, I give them my highest rating.
