I started using this product when I was nineteen with a little skepticism because of the price. I started using their 6.6 lbs box of SA8 on August of 1999 and I didnt have to go back to my supplier until October of 2001!! This stuff is so super concentrated that you dont have to use very much of it at all, and it doesnt leave your clothes smelling like detergent. It is also safe on your skin and has gotten blood, grease, and oil out of my clothes with out having to do multiple washes. The only thing about it that is bad is the fact that its not accessible in stores and you have to contact someone from Quixtar to get it. That can also be good because those people usually know their products and they can give you advice about stain removing because they have done their research as an IBO and the company does an outstanding job with keeping up and over powering the other detergents.
If you are going to spend money on laundry detergent you definently need to get this because it will save the ol pocket book. I honestly dont know what detergent costs now-a-days because I have invested in SA8 for 4 glorious years.
Overall, this product saved me a lot of money in the long run and I will never use anything else, ever! Use it and see the results for yourself! This stuff rocks the house!
