I haven't tried them but I would do some more research if you are thinking about giving them a try.
For starters, research has shown that most people don't need a "cleansing" regimen -- your body takes care of that naturally. Studies have shown there isn't a bunch of you-know-what in your body that needs to be "cleansed." I see one of the ingredients was probiotics, which can be good for you, I don't know if they are giving them to you to correct the cleansing or for some other reason.
It looks like a lot of people on sparkpeople.com are talking about them. I would check out those discussions. I would also google the ingredients. The scarier sounding the ingredients, the less likely I would be to consider it. It sounds like one is simply the equivalent of a lot of caffeine.
Not to mention that it seems to go against what Jillian supposedly stands for -- getting healthy the natural way, with diet, organic food and exercise --when they are promoting their formulas. It's a little disappointing to me.
I am always leary of any diet related product because so many get recalled for serious side effects and get pulled from the market. I don't want to be one of the one who gets in trouble before they figure things out.
Good luck in your research. If you do decide to give them a try, please be sure and let us know what you think.
