Actually yes, they are. Do better exist? Yes, for twice as much money if not more.
I've owned my Kracked Skulls for two years and I beat it to shit. I bail on huge hills and it crashes into shit constantly. I live in Burlington which is basically an enormous hill so to control my speed I'm always riding up on the grass, running over sticks and all sorts of shit. I hop around on it, do stupid shit with it all the time... and all it has are a few chips on the nose and a fuckton of scrapes on the bottom. They're durable as hell, they do not snap...
As for the designs... who cares? Make your own design. I bought grip tape and cut out pieces of it and made my own custom design, way cooler than getting a premade one from a company. Stuck some stickers on that bad boy and now it looks dope as fuck, took like an hour of my time. I may even remove the trucks and paint them metalllic green. Saves money, and it's custom.
Most importantly, however, they ride like a dream. Having the trucks mounted through makes it low to the ground which gives you more confidence and makes it more stable at high speeds. Sure, other companies do that, but it's rare and usually much more expensive. They carve nasty as shit, and they're just smooth, fun-ass boards. Don't knock what you don't know. Every person who's ridden mine says it's one of the best they've ever ridden. Here's some pictures to prove that you can make it look sweet with minimal effort... I love my KS board, and so will anyone who buys one.
