Will buy again!
I HATE scented items, included trash bags, and I despise air fresheners- but, the black tank needed treatment. These things smell amazing, I don't know how they did it. There is nothing worse than knowing something stinks, and the smell is trying to be covered by a more pleasant odor- this is not like that. These packets smell good and they don't have to try hard. They were bigger than I expected, one is supposed to treat 40 gallons. I figured we could add another one later in the season if needed as my tank is bigger than the 40 gallons.

Yes! It works! Camping potty savior
I am in a remote off grid cabin and have a little camping potty for overnight needs. I have been using it for over a year and never put chemicals or anything but soapy water in it to clean it. But now despite not ever going number 2 in it, it had gotten really stinky to the point that every time I opened the lid to use it, it would stink up the bathroom. I was skeptical but decided to toss one in (with a little water) after cleaning as usual. I am happy to say my potty doesn’t stink up the bathroom anymore. Smiley face! The pouch dissolved quickly and the ‘alpine’ scent is pleasant although not what I expected as a pine scent. But still even though it’s not the alpine I wanted, it still smells clean and fresh. Highly recommended.

Didn't care for the scent
They seemed to work fine, the smell after taking one out of the package was not to my liking. You really couldn't smell it after it was in the holding tank. I will get a different scent next time.

Bio-Pak Holding Tank Cleaner.
These are effective in ensuring that our tanks are cleaned out. Relieves any odor that can be smelled after taking a longer camping trip. Dissolves easily, no residue left in toilet bowl. Will use again.

Powder. Disinfectant. Black toilet tank
I didn't think this product would be so effective, especially for the price. I tried several products in my RV's bathroom because there was a constant, unpleasant sewer smell, and I found this product. It's been great for cleaning the black tank; it eliminates the bad smell and keeps the bathroom fresh. When I feel the smell starting, I put two or three balls in the toilet at night, and the smell is gone. Pretty good.

Works well with out added chemicals
Excellent product. I highly recommend it. Manages oder well and turns everything to liquid for draining, with out chemicals that cannot be removed in the sewage treatment process. We initially had minor odor issues, but have realized that with any cleaner all fans sucking out air from the camper will suck out air form the toilet into the camper. We also realized that the Thetford toiled provides a helpful sealing action when flushing. So in addition to using this or any product: turn off all of the out take fans and close the lid when flushing. I It seems to work well for 5 to seven days, the maximum I wait before emptying the tank. If temperatures are 95 and above for several days you may want to use Porta-Pak a chemical based produce. Finally, a note on the use of bio-pad and cleaning agents: Bleach based products and many other chemical based products will kill the enzyme that is the basis of this product. I use Green Works and this seems to be friendly enough. I use other products to clean the toilet just before I dump. I suspect that some to the less positive reviews may relate to this issue. If you are not going to use "chemical" bast agents you have to use similar cleaners. Most additives on the market will reduce the odor associated with raw sewage, but none willl make it smell like a bed of flowers. This product does a great job and it will not have to be removed during sewage treatment. (In most cases they are not removed, just diluted.) Nor will it harm septic systems. (A final note: When talking with manufactures about sented products they note that the scents are for the customers when they open the package. The scents are totally lost when the product is sent into the tank.)
