"This is the only product I use. I live in my 5th wheel and it was a 2007 when I bought it in 2024. So the tank was not great. Using this product and all of the tank products, my tanks are like new. I don’t use anything else."
"This is our first time buying from Unique Camping Marine and we’re very pleased with the customer service and the price of the digestive product that we use. We will definitely do business again."
"I love the products your company has to offer. . I will definitely keep buying"

"Best on the market. We have tried them all and these products beat them all. The new packets save space and time. We had sensor problems since day one with our TT but after using restore-it they work like they should!"
"After using another product, it was a simple decision to move back to RV Digest-It. It does a far superior job of liquefying solid waste, and toilet paper. It is also very effective at reducing odor, and keeping tank sensors functioning properly. We will not consider changing products again"
