WOW, WOW, WOW, We are new RVers and Unique is amazing, I LOVE that it's natural with no chemicals to worry about if it spills or gets on me nor harmful to the environment. It's easy to use and doesn't take much. It's affordable and comes in sizes to fit needs, I'm not one that leaves reviews but Unique is worth talking about.

I have been living full-time with my wife in our fifth wheel toy hauler for 10 months. I used several different black tank products until I tried RV Digest-it. It's the best. Just over night everything is liquefied and drains easy. I won't use anything else from now on.

We will never use anything else. This is by far the best product ever. We have been RV'ing for 20 plus years and have never come across a product like this.
