Good, proven product.

These pods work great, don't need much storage space, smell great, and keep odors from happening in the Black tank. I use the liquid for the Gray tank, and Black, too. The liquid does not freeze, so it can be stored in the "trunk". The bag on the pods does not always stay closed. I dump my tanks twice (G) and once a week (B) without any problems.

Was new to the motor home living the first time using and thought it was great. Then I tried other brands to try and save money, but I ended up using more of the less expensive brand because it just didn't control the odor like TST CAMCO

This TST works perfectly in my RV. I love the sealed individual pods,I never get it on my hands. It breaks down solids perfectly. Have not had and drainage issues since I started using it. I highly recommend.
