I have used this product multiple times with excellent results every time. I tried Rhino Black 3k and it didn’t do anything for me. Now i have not tried any other Rhino product so I don’t want to be unfair. But I know for a fact that ONE MORE KNIGHT works great for me. I recommend buying a single pill before dropping money on the case. I pay $18 per pill locally. So this whole package is a great deal but I find that different brands effect me differently. One More Knight is my favorite.
