Not sure, I just picked up Your Shape 2012 (which is very similar) last week, but haven't had the chance to use it though.

I've read a lot of people being happy with the UFC Trainer, though it obviously won't pay the dividends a full gym workout would.

Realistically, if you can stay motivated (my problem) and keep up with regular exercises that's enough for most people to stay in decent shape and generally feel good about themselves.

 

I thought it was pretty crappy.

 

There are not very many audio files for the trainer so they repeat themselves a lot. Loading time between exercises are a little longer than I like for the dynamic work out.

Maybe because I am a fat man, but it does a poor job of registering some of my movements so I have to do the same one for three minutes just for it to allow me to start the movement.
