Review on Enhance Your Laundry Experience With Purex Crystals In-Wash Fragrance Booster In Fresh Vibes - 4 Pack 21Oz by Shah Moser

As far as similar products go, I find that this one is the most cost effective. I will say that they're different than the higher end similar products. The higher end are almost like a mixture of lotion and wax together (best way to describe it). These are more like a harder plastic (again, best way to describe it). They both perform the same results, but in a different way. The packaging could be half the size, because that is how much is in each tube. Overall, for the price, it really doesn't get better.
