It is pretty simple to use and other addons work well with it. It is useful if you want to make an underground base. You can teleport between each of them if you are below or under a elevator. Jump to teleport up, sneak and interact with your hand to teleport down. The limit between each elevator is 16 blocks.(I will higher it later). The elevators can be colored in 16 different color.To work,they need to be the same color.Just change the color of the wool in the recipe.This block needs mid-tier ressources to be crafted:8 Wool,1 Enderpearl.
