I bought this for my birthday for a fun approch to getting fit and losing some weight. I think that this is brilliant as it is fun for all the family. Creating your own Mii is also very fun and i love playing on the Wii as it is interactive, unlike any other way of getting fit. It has a facility that allows you to keep track of your weight loss, and you can do a daily body test to make sure that you are making good progress. It takes into account your height and weight and gives you a BMI, which is also very good, although sometimes it can be inaccurate, as muscle weighs more than fat, so dont be disapointed if you come up as overweight if you know you are not. Other than that i can not think of any faults with this machine, and i think that it is a great fun way to actively lose weight.
