Excellent Product!!

Doing its job so far. I live in the RV with my two sons, so it holds well as far as odor but it’s doesn’t break down as well as it says, but the tank fills pretty fast too, so to be fair it works decently.

Like it but the price at Amazon is double the price at Walmart

Great product works great and has a nice smell. This is the second product i have use to help control odor in RV. It works MUCH better than the other one I tried. And you use less of it.

Definitely improves black tank odors, but it didn't do any more than the cheaper alternatives from the same manufacturer. The big pourable container makes it way too easy to use way too much product. We're using like 4x-6x the amount we intend to trying to pour directly from the bottle. So I suggest getting a little 2oz container to use to get the right amount.

We have had a camper for about 4 years now and this is by far, our favorite toilet chemical.

I like Rhino for my RV because it eliminates odor. Even sewer gas.

Works good and only need 2 ozs per tank, so there are potentially 32 tanks worth in this. Way better price for the amount than anywhere else I've bought tank disinfectant.

Not sure what is going on with this toilet chemical, it seems to have bits of black flakes in it. Not sure if we got a bad bottle or what but it's kinda gross. Doesn't seem to keep the smell down like other brands we have used. Glad I only bought a small bottle to try out. Will be switching back to the old brand we used when this one is done.
