I haven't yet, I was going to wait until after Xmas to see if I can pick it up in the sales. I've got Davina's other DVD's (except for the pregnancy & post natal one) and really like them, so I thought it would be a good bet I'd like this one too.
I tend to find that they do work you quite hard, especially the 'Power of three' one, but it's well worth it for the results.
