I have tried it. Taste wise it is not bad. However, I found it to be overpriced.
I compared it, from a same serving size standpoint, with Jiff peanut butter (the best outside of natural), and found them to be comparable (almost the same amount of fat, protein and carbs....a little variation, but not much). Granted there are some relatively significant differences in the type of protein and fat, but IMO these are not significant enough to warrant paying 5 times more than I could for a jar of peanut butter.
