A Nintendo Wii coupled with a balance board is wicked fun! Ours was purchased along side the wii fit game and I can safely say its well worth every penny. The board itself is extremely responsive, much more so than i expected. Sensitivity and movement control is usually set within a game by following certain movements as instructed. I would recommend investing in some decent rechargeable batteries to go with your balance board as it does eat through the double A's at a fair pace (it requires four at a time). Games such as wii fit and Shaun White Snowboarding really make the most out of the wii balance board and are great fun. Another downside is that uneven floor surfaces tend to upset the wii balance board somewhat - even deep pile carpets can cause an uneven floor surface. To conclude, this is a well built, sturdy piece of kit for your Nintendo wii - and great fun to use!
