Proud Biz user - great value!
Biz works good compared to similar detergent boosters. It helps take stank out of hard worn clothes that had alot of sweat and stains. I usually throw it in the whites and they come out looking good. Best of all it has a nice light scent that let's you know you used it. I get it for $4.99 for the largest box so it is definitely a huge value product.
