This stuff really works! I had that OFF smell in my beautiful camper which was such a Debbie Downer, even with an empty tank. Made me sad....within a day the stink was gone, and now the tank is 3/4 full and still no stench! Makes my happy place happy again! Its true it helps the sensor. Just b4 adding to my Black tank that I just had emptied, my sensor read full....within that same first day of adding, my sensor read empty witch I know was true because I had just paid 80.00 to get pumped out! Highly Recommend! This product is not gonna have your camper smelling of roses, more importantly, there is no longer ANY smell! Love it!

Let’s be honest—when your black tank’s acting up, no one’s in a poetic mood. But after using this stuff? I was ready to write it a love letter. We had a clog that was so bad, I considered selling the RV and taking up hiking instead. But this bottle of enzyme wizardry came in, took one look at our tank, and said, “I got this.” What I Like: • Cleared up the kind of clog that gives RVers nightmares. • No more lies from the sensors—it actually reads correctly now. • Smells fresh enough to not question your life choices after flushing. • Easy to measure, no guesswork, no mess. What I Don’t Like: • Nothing at all… except maybe that I didn’t find it sooner. My Final Thoughts Let’s wrap this up with a little verse, because it deserves it: When your tank is full and the smell is stout, This little bottle will bail you out. It breaks down waste, it clears the air, It saves your trip (and nose) from despair. Tip for Buyers: Wear gloves. If this stuff can dissolve toilet paper and waste… maybe don’t trust it to be gentle on your hands. 😉

So it didn't cure the blockage that I had, but I can only assume it did help some. This was a blockage from the previous owners and it didn't take me long after moving in, to find it. I was hoping this would do the job but it actually took an RV tech, 2 hours, and a $300. bill to completely fix it. I could tell it was trying to dissolve everything but it was not going to happen. Had it been just a normal clog, I think this could have done it. So for that reason, I am giving it a 5 star. Nothing but a high powered pressure washer was going to solve this issue.

Does NOT help with odor. Waste of money. Update: after writing this review, I must say that the company stands behind their reputation. They contacted me and gave me a full refund. They also offered help in reference to product usage, etc. very good company and I will continue to order products from them.

We have used other products in our camper and nothing compares to Unique Digest it. We have not had any issues with smell clogs in our black tank since using this product. The product breaks down solid waste and toilet paper. Everything that comes out of the black tank is liquified and moves easily out of the tanks. Since using unique, we have also never had an issue with sensors miss reading the levels. Highly recommend this product if you have a camper or RV.

By far the best product I have found for my waste tank! Believe the videos(I have saw one with two other products and this one using hard dog food which this blew it out of the park) believe it if you have seen them online with comparisons to other brand name products.Both liquids and the pods. I will never use anything else!!

Following instructions, 3-4 ou to start black tank then add 2 more ounces every 3-5 days (I used 4 days) I can’t say this product reduces Oder better than other blank tank products and one is using a significant amount of the bottle for a 1 tank load. I used 14 ou total for 1 tank 1 person; nearly half the bottle. So by their instructions I get 2 uses or two tank treatments. Now there are some benefits. I started w/ their cleaner. It did not clean my gauges but dumping this first used tank I would say the sewerage was much more viscous (more liquified) then with other products. My tank rinsed with few rinse cycles too. For 14 ou of this treatment I would expect so.

I don’t know if you’ve ever had a poop pyramid in your RV? I bought a used one that was plugged! I thought it was going to be a super hassle unplugging it! Best $40 I ever spent! It took the whole bottle, but it’s a great product! Even just getting rid of the smell was worth the price! The stuff works! Just make sure you let it sit and do its job. It’s NOT gonna work in one day! Let it sit for a week or more adding little bits more & small amounts of fresh water!! if you can agitate it even better! Then drive it like you stole it to the Sani station! Reveres flush & it’s Clean! Worked on the gray water smell too!

We bought an old RV that had been through many owners. We had trouble emptying the tank- it would not drain at all! My husband was having nightmares thinking we would have to replace the whole tank. We added this product, waited 3 days and problem solved! Everything in the tank dissolved and it works like new!!! We will definitely use this again!!!

I have ordered this 3 times. It’s very effective in solving the problem with “waste buildup” and waste coated sensors. It dissolves toilet paper build up. I simply follow the directions and use it every time I dump the black water tank. It’s very effective in eliminating the odour from the black water tank. Highly recommend this product.

Tried several different products - found this one works MUCH better to digest waste - hardly any solids left when dumping black tanks!
