"I have used Unique Camping products for our black tank from day one. We never have any odors or overwhelming fragrance. It’s simple to use and they have great guidance for maintaining all of the tanks in our 5th wheel. They’re also very helpful if you call for advice. I use Store It once we’re home because it guarantees the camper doesn’t get stinky while sitting unused. I would never use any other products."
"We left the rv for almost 2 weeks and for the first time we came back to no smells like we used to with our previous products we used."
"As always, I toss Store-It into the tank whenever I will be away for more than a month. It keeps the tank smelling fresh even in the 100F+ temps, and when I clean it out, it's totally clean."
"im not sure yet. havent gotten anything to light up yet. put 8 ounces in 80 gallons and a week later dumped the rest of the bottle in."
"Appreciate your desire to get product feedback, but Store It performance really can’t be judged after just two weeks on boat. Will be back in use in 5-6 months."
"product worked very well"
"My trailer doesn’t sit still more than a few months, but I have never had an issue with sensors, clogging or smell since using was Digest-It while traveling and Store-It when it’s parked for a for a few weeks or a few months. This relieves all stress from tank maintenance and its apart of my routine now. The product has proven itself and I wouldn’t use anything else."
"Worked better than expected. Great product!"
"Always only use these products!!"
"I left the product in for 20 days and when I drained them I certainly saw lots of waste come out of a supposedly clean tank. I am still getting tank level reading issues on one black tank though"
