I ordered the black board right after I tried it out at my karate school and it's the best money I ever spent and I would rather get these boards from karate depot than century because it's cheaper here. When I first got the board it was really hard but after some training and focus I can break 2 black boards so very soon I'll get the whole series so that me and my friend can try to brake them all at once. Just one thing though if you do try to brake any more than 2 boards you will need a clamp, because the boards tend to bounce a lot
