Reviews

When your product is on top . Reviews show lack of confidence

"Trust me, I know what I’m talking about. You should spend more time protecting your product and the time and money you spent in the chemist lab developing it. You’re already ahead of your competitors (Thetford aquakem)your product will speak for itself instead of showing vulnerability and lack of confidence . with these reviews, you send I’m responsible for four Olympic medals in Ski racing product development. Being on top and Hard work to stay there . is pay off, not justification. you don’t need to be told how good you are when you already know it. I believe that’s counter marketing. when you have such a good thorough effective and efficient operation and a product to back it all up with."

— Will W. (5/5)

Happy Longtime Customer of Unique RV Products

"I have been using your products for the past 4 years. I live in my RV full time and I have been a very satisfied customer. I have yet to try the upgraded RV Digest that I recently bought, but I'm sure I'll be more than happy with it also."

— Constance B. (5/5)

Trust it works

"Since I have been using your product, I have not had any problems with my black tank. I trust it better than those 'pods' and it lasts all summer and then some."

— Frank S. (5/5)

Effective product

"This treatment works pretty well. I like it over using the drop-ins or other types that don’t work as effectively"

— CHRISTINE H. (5/5)

Sticks not as good as liquid

"The stick packs just don't work quite as well as the liquid. Planning to try mixing them with warm water on my next round before flushing, maybe that will create the same fresh and clean smell and clear the sensors better, like the digest-it liquid always does."

— TJ C. (4/5)

Love the digestit

"I have used digestit in the bulk powder form for 10 years and love it. Unfortunately the bulk powder is not available anymore. I purchased the liquid to replace it with the built in measuring. The company has been great."

— William C. (5/5)

RV DIGEST-IT

"so far so good. I really like the convenience of dispensing it."

— Dianne D. (5/5)

This stuff is great!

"After doing some research, I bought this for our first camping trip back in 2022. They have great “how to” guidance on their site and using their products and following their instructions has kept the camper tanks odor and problem free ever since. I would never use anything else."

— Meredith D. (5/5)

Best out there

"I use the tablets with the liquid. I rinse the full tank 1x a month minimum and get a full clear water. I have a used 2007 5th wheel I’m full time. Once I empty (and it clean the tank) I put in the liquid. Then every 3-5 days I drop a tablet or 2. I use angel soft toilet paper. The tablets help with keeping the smell down and break everything down. I know I use too much but I don’t worry about my tanks any more. It took me some time to get it to drain clear water on the 2-4th rinse but the tablets help in between the rinses."

— Suzy (5/5)
