This product looks great but unfortunately it doesn't perform as well as it should do. The centre of gravity is inaccurate but worst of all is the weighing function, according to this board I lost almost 2 stones in weight compared to the original board and my own scales. I do not know how it will perform when used within the games as I didn't get that far, it was so inaccurate I just repacked it for immediate return. This may be just one bad unit, the rest may be OK but I personally will not try another one, the choice is yours. To sum up looks great but the performance lets it down.
