I cannot say it is good or bad, I can say it is it mostly based marketing and does not match the Wagyu I know. The beef is a cross-breed, grain fed and 600 days. It good and tasteful but far away from the quantity in Japan. Gimmicks sell, the real deal is always more complicated and more expensive.
