Weapon's range (thunder maul)

What range has the thunder maul in d2r?
I saw on different sites that it has range 3 in others has 2 and others say it has 5.
What is the real range of this weapon and is it worth to make botd in it?

The Thunder Maul is a [Two-handed] Elite [mace] It is also a member of the [hammer] sub-class.

Thunder Mauls, while slow, hold the honor of the highest average damaging weapon in the game in terms of base stats, but the Strength requirement it inflicts upon the user is very steep- perhaps the highest requirement in the game.
