funny you would ask. its been about 6 months ago, but one evening when I ran out of medium grind. I put kava Candy to the test. LOL. Here is what I did. I took a coffee grinder and ground up, about 2 boxes of candy (16 pieces). I then mixed it in with a little juice, and gave it a stir. next, I slammed the grog, I had made. It was quit tasty. It did end in a nice medium crunk.
I was quit happy with the results. Now, is it as strong as grog, per piece? No. But the nice thing about the candy is, you don't always need a heavy crunk to eliminate stress. So, I find that the candy works good, in situations, when getting crunked is not applicable. Such as at work, or at a event.
So to answer your question, yes they work well. But it would take quit a few of them to equal a regular kava. But for the price, I find that they are worth it. I often order the Candy. My wife really loves it. She like to suck on them during her work outs. I also like them when I am working hard, and getting crunked, would slow me down. Much Love Roaddog....
