Tesco fat and carb blocker???

[Lotty Big Botty]

Hi all

While I was stocking up on my usual slimfast and ultra slim shakes in tesco yesterday, I noticed that tesco's ultra slim range now do a fat binder and a carb blocker pills.

I was wondering...
1) if anyone had tried either of them?
2) are they any good?
3) can they be used in combination with the slimfast/ultra slim diet? And would they still have the same effect?
4) which you think would be best... Fat or carb blocker?? (apart from weekends I don't think my fat intake is too terrible!!)

Thank you if anyone can help, currently I'm clueless!!
