Product review (3 stars): It's OK but is diluted so you have to use two or three times as much
There are other brands on Amazon with the same active ingredients but 3 times the strength but only 50% higher cost.  I didn't notice that before I bought this.  I could have paid more attention and understood that this was a diluted form of the product so it's not that they were dishonest or I was cheated; I am giving three stars simply because it is a diluted product and the stronger versions are a better deal.
