Of course Mastodon is hard to use. They're really big, for starters, and if you don't have the right ladder even getting on is a challenge. Then they have to be fed a hay bale or a wheelbarrow full of cabbages every hour. And depending on where you use Mastodon, you may be responsible for cleaning up all the droppings.
But once you get over those things, it's really pretty great. Stinky. But great.
