Carb killa bars?

Hi guys, I'm new to this whole keto thing, a week in and feeling pretty good, but sometimes old sweet cravings creep up on me.

I looked at these Carb killa bars & was wondering if they are any good for keto? Someone told me a bar is only 2 net carbs? Not sure how true that is.

I'm in the UK so I don't have access to Sonethung like Phat fudge.
