I`ve got some Tanita scales. You can get normal ones but they do expensive ones that can measure BMI etc as well as weight. They are a bit costly but they are worth it.
I've seen that ad with Helen Mirren, I've not really took much notice of it, tbh. I'm not sure if we have the necessary slot/sockets to accommodate a console ....I'm guessing it's gonna be quite big, like a DVD player?
I have some Hansen scales. I weigh a different weight all around the house, the best place is in the conservatory, I've weighed our holiday suitcases there which have tallied with the airport check in. I guess it's time I got some more.
Son had one, not the wii-fit but just a wii. Great fun was had playing tennis, skittles, golf. The only room which was needed was to avoid the one who had the remote so you didn't get smacked in the kisser :)
