Doesn't smell like a public restroom and supposedly is septic-safe. Haven't noticed any odors since we started using it. One jar lasts a long time too.
I've used these with no ill effects.

We use the Geo Black Tank method and put in one bucket of hot water with calgon, Borax, and Dawn detergent after each Black Tank dumping. Absolutely no issues with smell or our cheap factory tank monitor.
