Smell

Ease Of Use

Value For Money

We just returned from 10 days of camping.  First time we used this product in place of what we normally buy.  It worked very well.  Seemed to dissolve all the paper . . . which usually doesn't happen with some other brands we've tried.  Kept the sensors clean, so we knew just how full the holding tank was without guessing.  Not to mention, it's so easy to use - no measuring!

Actually worked well

[This review was collected as part of a promotion.] This product truly helps with the oder problems in the summertime when the AC is running and you flush the tank and the AC pulls the smell out of the black tank.  But this product eliminates the problem with the stench.

This product helps with the Black tank

I live in a Traiker full
Time it's beautiful but yet the toilet is a tank underneath so you need to use some biodradable pod or liquid abd I have tried other brands and this brand in other sents abd this one is great great sent and reakky breajs down everythung

[This review was collected as part of a promotion.] I've been using for years .

It worked and it was easy to do and it made a big difference

Opened black valve, wouldn't drain. Prepared to run snake through opened valve, but decided to give these cellulase enzymes a try, since it was likely, a paper clog. Threw two packet in almost overflowing toilet. Two hours later, toilet is unclogged, and I didn't have to snake it! Needless to say, one of these packets will definitely be added after each dump. Great product, great price!!

Toilet wouldn't drain

We really liked the convenience of having a tablet vs. the liquid form of treatment that we used in the past.  The price seemed good, that is why we bought 2 packages.  Also, package states that you have the option of using any type of tissue rather than the biodegradables sold for RV's.  It seemed to work as promised so we will continue to use this product

Very pleased with the product

Have not used it yet but we'll have them in emergency
