I LOVE, LOVE, LOVE it! It is lot better than the Original Zumba dvd version in my opinion. I dont have the 1st and 2nd of the wii version. It did not appeal to me when they were new on the market. After reading some negative reviews on top of it, I thought forget it, I'm not buying the wii version of Zumba. After a while, I get bored with the songs in the Zumba dvd itself! I need something new to combine with the basic steps of the Original Zumba. Thanks to those who wrote the reviews for the above product, I found what I was looking for, to boost up my Zumba regime!.As any product mostly be, the latest tends to improve and supersedes the previous.Most points have been mentioned by the other buyers so, I am just adding on a bit more here. Each song comes with low, medium or high intensity indication. Which I find very helpful. There are few songs which are actually meant for warming up or cooling down...fab! On days where you want to go easy, just pick up those low or medium songs, likewise, if you are feeling energetic and want to run the house down, the selections are there. What I love most about the Zumba Core is, there is no timing on the screen. It puts me off seeing how many more minutes is left before you complete the task. Lastly, you dance hands free ...remote in the belt's pocket and you are good to go. No holding remote business, no holding stick, nothing! Just dance! (Having said that, I think I'm going to ditch the Zumba dvds after this..lol!) All in all, it was worth the penny.
