"Really works!"
"I must say, this stuff is amazing! I had an extremely compacted tank in my RV (not a drop would come out of the valve). I put this in the tank along with several gallons of extra water, waited about 96 hours, opened the valve and the tank drained straight away! I flushed the tank twice and added some of the Digest-It and all is good again. Thank you so much for an outstanding product!"
"Always works great."
"Unique camping + marine is the best company out there by far! The customer service is unlike any other business I have ever encountered! They walked me through the process and the education I received from a phone call was astounding! Just as they had predicted their product worked perfectly! I will always let campers that I know that unique is the best brand by far!!"
"Worked just fine"
"Lost my tracking information called Tara and she resent it. Very friendly customer service products nicely packed. Definitely would recommend them."
"Works just like it says"
"Haven’t used it on a real clog but it does seem to help slow running kitchen tank drain in the RV."
"I love this product! It’s the only I trust to get the job done. I’ve tried other products but come up short of accomplishing clearing the problem. I can also count on Clear-it to flush the problem out! Would only recommend this product and to everyone who will listen."
"I never actually had to use it yet . I will keep it on hand"
