This Company definitely exists the reviews are awesome on Amaazon here is a couple of reviews from customers who purchased their product,
Too simple to use. I've regularly used other septic additives, and didn't ever see 100% of odors disappear. I wasnt expecting it, but surprisingly after the first week we noticed, hmmm, the odors weren't around any more. Probably been around a month (not sure, maybe more) no odors coming up. Very please such a small tablet was effective. Very pleased
