This is a great product.  We have been using it for years and it really breaks down  and liquifies the waste in the black tank and helps tremendously with the smell in the gray tank.  AWESOME product!!

Great product

walmart.com

5  years as full timers in same rig: a Keystone Montana fiver.  As newbies, we discovered no septic issues once we started using Happy Camper exclusively, along with dissolving rv TP.

Happy camper   rv TP = No problems 🙂

This is the only tank additive that works. Been full time RVing for 3 years and found this product to be the best and worth the money. It may not be as convenient as other brands, but it works!

Great product don't bother buying other brands

This stuff is amazing, no smell, it even cleaned our sensor that had been showing full for several years and it's now working properly. I won't use anything else.

This product much works better than others I have tried.  It keeps odors under control and for a longer period of time than others.  Only downside is it is more expensive than other products.

Works well to control odor

Works great for short and longer periods. Cost keeps going up.

Works Great

Great

This is the BEST RV tank treatment! It's absolutely true that there's no smell when dumping your tanks. It digests waste well as advertised. Don't waste your money on any other product!

We've been full time for nearly 10 years.  We've used Valterra Odorlos for that entire time.  After reading glowing reviews of Happy Camper I thought I'd give it a try.
As I wanted to give it a fair test, I flushed the black tank 3 times and let it set 24 hours nearly full with a black tank cleaner before dumping and flushing one more time.  I added Happy Camper with admittedly high expectations.  Not impressed!  We now go a much shorter amount of time before we start experiencing odor in our coach.  When using the Odorlos if we got a sewer smell it was nearly always because the kitchen gray tank was full.  Very rarely was it due to the black tank.  I'll finish the container of Happy Camper but I've already ordered a tub of Odorlos as a replacement.

Disappointed
