Wii BOSS controller

The Wii BOSS controller case is yet another pretty redundant accessory for the Wii, as it slips over your Wiimote and supposedly makes it a whole lot easier to grip as well as mashing those buttons in a frantic game of Mario-derived origin. In some ways, this is pretty much the Classic Controller albeit with an integrated accelerometer. It seems as though the bulk makes things rather unwieldy, and it would be good if you had some rather large hands to take full advantage of the BOSS controller. Would you fork out $10 for this or rather save it for the next game purchase?
