As a novice to these types of games it was easy to use and understand, especially considering I had a bleary eyed 5 am start. The routines were easy to follow and the "learn it" features are great. My favorite so far is boot camp, lack of coordination made latin dancing frustrating, no slow step by step. You would have to run through the "learn it" a couple of times to get it. My other issue with this is that unlike most workout DVDs there are no modifications shown. I have challenges with my back and knees and some exercises such as plank push up are not for me. But if you are comfortable with ignoring the score you can do your own modification, after researching proper form, and have fun. The expectation is that over time you'll get better and your score will improve. But there so many options there is something for everyone. The calories burned is way off. I use a polar heart rate monitor and the system noted a 80 calorie burn my polar calculated 336. The Kinect interface is excellent and it will help you to learn and maintain proper form, important to minimize injury. So not as great as having a personal trainer coming to your home at 5am, but it is the next best thing!

Would have preferred more concise explanations for some of the rules. Other than that it was very informative.

Complete Junk. The firewall are blocking things that it's not supposed to even though the rules are set to allow access. It even blocked my printer, prevent any of my home network PC to see each other, stopped my team viewer and other services etc. All were set to allow access in the firewall rules. Once I disabled the firewall, then everything is back to normal. Do not buy this.
