This product did not work good, I will not be purchasing again. Did not help completely with the smell.

These liquids are much easier to use than the drop-in pellets I've used forever. I clean the black tank every Sunday, and these come in an 8-pack of liquids, which will last me eight weeks or two months. That's okay; the price is nearly the same as the pellets. As far as I'm concerned, it's a good buy and much less messy [the pellets sometimes break in their package and make a mess].

This was the first toilet chemical we bought for our camper and had no issues with any odor. Decided to try another brand in tablet form bought locally and only used those for two camping trips before we couldn’t stand the smell any more. We ordered these and they arrived the next day. This brand keeps our toilet odor free. These will be the only toilet chemical we use from now on!

I live in a RV and a bad smell is not what I don’t want it to smell bad

This is one of those types of products needed by RV owners with a toilet and black water holding tank. It works as intended and I sometimes (not always) find that Amazon has a more competitive price than RV dealers and hardware stores. Almost like all the other RV products from this manufacturer, they are over priced for what you get but because you need them and want to be fully prepared for your road trip or camping adventure, these are a must have. The price can sometimes fluctuate on Amazon so I usually stick up on these because I know I’m going to need them all.

I have tried a few different brands of deodorizer. This is the best liquid RV toilet holding tank deodorizer I have used. To be on the safe side, I use one a week even tho there is never an odor.

We've been using these Camco TST single-serve toilet treatments in our RV toilet for ~2 years now. I love the individual serving size, just open the bottle, drop it in the bathroom and chase it with a bit of water. We add it every week or whenever we empty the black tank. The orange smell is pleasant and helps mask odours from the black tank. I've also found that it does a great job at helping to break down the contents of the black tank, including toilet paper.
