Bests & Worsts Reviews from Amazon

Excellent product. I am new to Rv'ing and I was informed to purchase some sort of black water tank chemicals. I looked over numerous reviews and ended up here. I have only used them a few times but so far so good. Believe me when I say these work. I destroyed my toilet at least 5 or 6 times this past weekend and we couldn't smell a thing. Not too mention it was like 100 degrees out. If these things can tame the combination of my bio-hazard waste and 100 degree temps you've got a winner in my book. Too bad I can't give them 10 stars.
