Summary: I have purchased 2 of these items now. Both times I have no communication between the sensors and the USB key. I even tested them all out on a friends Wii to make sure mine was not faulty. The problem is the game WILL NOT WORK without the USB key. ALSO the online communities and help were all cancelled by EA Sports within the first year of the product coming out! Not good. I had such high hopes for this product after my experiences with the previous versions.
Summary: The straps are very uncomfortable... the game stops if you do not do the exercise exactly right... and even if you do... very very annoying... not a good work out as the calorie burn is no where near what they tell you it is... this game stinks... period!
