I did try a few of their formulas, but it’s been so long I don’t remember which ones. What I can say is that the results did not impress me.
I don’t know if that was because HAX may have been over-hyped, or because they just didn’t work for me.
Thing is, I’ve seen formulas get great reviews, yet for me I’m just not impressed.
Aqua Vitae gets great reviews, for me it’s alright.
Other people dislike Bad Wolf, but it works great for me.
The way I think of it is that reviews can be helpful for guidelines about what results I might get, but ultimately I have to see for myself what happens.
