HAPPY CAMPERS RV Holding Tank Treatment - 130 Treatments

We have been full timing at the Gulf Coast of Texas since May and not once have we had any odor issue. It breaks down the contents better than most. Extremely pleased and we would not use anything else.

I really like this product! We are full timers and there is no smell!

My Dad recommended this to us several years ago because it is the only RV tank treatment he will use and my parents do a lot of traveling. It is very easy to use and our bathroom does not have any odors. I have tried other products and this one works the best!

Easy to use, no odor, cleans the tank sensors. Best tank product I have used in 16 years of RVing.

Very good product easy to use

better than all others we tried

Ive used different products over the years but when I found this one I stopped looking. Nontoxic and does what it says it will. Recommended.

Good holding tank product for an economical price. Not as easy to use as tablets or packets.

We have used this stuff for years. Even in 100+ degree weather there is are no foul odors from the black tank and no stink when dumping the tanks. It is formaldehyde free, too.

No surprise based on other reviews. This is the best black tank treatment on the market and I feel like we’ve tried them all! And we’re full time RVers.
