    • Works awesome
Been using this for a few years. It is the most effective at controlling odor & disentigrating waste. Happy campers is easy to use, works awesome & hopefully better for the environment.

    • So satisfied!
We have a camper that we may get to every other weekend. One weekend we had our 6 yr old grandson who I told to use the restroom before the long ride home. He forgot to flush and I didn’t check. The following weekend going back, it smelled like old urine near the bathroom. I flushed and followed the instructions for Happy Camper. It works amazingly! We had no smells even holding the flush pedal open to fill, no smell! I also treated the gray water tank. I absolutely love this stuff and will keep using! I’ve used other products in all the years we’ve been camping and nothing ever worked like this! ... show more

    • Use Happy Camper and eliminate the poop pyramids
As an avid RV enthusiast, I recently tried the Happy Campers RV Toilet Treatment and I am very impressed with its performance. The treatment is very easy to use and quickly breaks down waste and toilet paper, leaving my RV's holding tank clean and odor-free. I appreciate that it is made with natural and biodegradable ingredients, making it safe for the environment and my RV's plumbing system. One of the things I like about this product is that it is very effective at controlling odors. Even after several days of use, my RV's bathroom still smelled fresh and clean. The treatment also helps to extend the time between pump-outs, which is convenient when I am on longer trips. The treatment is also very affordable and provides good value for the cost. A little bit goes a long way, so a single container lasts for several uses. Overall, I am very satisfied with the Happy Campers RV Toilet Treatment. It is a reliable and effective way to keep my RV's holding tank clean and odor-free. If you are in need of a quality RV toilet treatment, I would highly recommend giving this product a try. ... show more

    • Does not work for Porta Potti
Initially i bought happy campers treatment to be used for my thetford porta potti 365. i only use the porta potti for no. 1 and only needed to be emptied around once a week. previously i use walex porta pak so i tried switching to happy campers treatment because everybody was singing praises about this product but unfortunately for me, happy campers treatment is unable to cover the odor because i could always smell urine whenever i use the porta potti and by the end of the week where i empty the waste tank, it reeks horribly :( i am not sure if my dosage is not enough or is it because the previous usage of walex porta pak has some residues remain that lower the effectiveness of happy campers but the waste tank smell horrible at the end of the week when i empty it. i tried cleaning the tank and give another shot but the smell is still bad and emptying it at the end of the week is horrible. after reading that happy campers treatment requires oxygen and does not do well in airtight environment like a porta potti, i guess i will stick back to walex porta pak for my waste tank. so i started using happy campers treatment for my grey tank instead and to my surprise, it works amazingly well! usually my grey tank will smell bad at the end of the week but ever since using happy campers treatment, the grey tank has no smell at all. it's a miracle and emptying my grey tank is a breeze now. ... show more

    • This stuff works great!
Our motorhome sits for weeks at a time waiting for our next adventure. Before using this product I had to not only dump the tanks but rinse them out to keep the smell out. Now there are no worries, I left the tanks 1/2 full from our last trip to see if this product was really making a difference. I closed it up for a 9 days in the hot sun. When I opened it up I was pleased to find no tank odors at all! Yes I am a fan! ... show more
