The Camco TST MAX Camper/RV Toilet Treatment Drop-INs offer a convenient and powerful solution for managing RV septic systems. The drop-ins boast a reactive odor-eliminating technology that controls unwanted odors for up to 7 days, ensuring a fresh and pleasant orange scent. This product is particularly effective in breaking down waste and toilet paper, aiding in preventing clogs and improving waste digestion, which is beneficial for sensor performance in black water tanks.

One of its standout features is its ease of use; just one drop-in treats up to a 40-gallon tank, making it simple to use without the need for measuring or mixing chemicals. Additionally, it’s compatible with various systems, including RVs, boats, and portable camping toilets, making it a versatile choice for different camping situations. The treatment is also biodegradable and safe for septic systems, emphasizing its environmentally friendly aspect.

However, some users might find the orange scent overpowering if they prefer a more neutral smell. Also, while the product is effective, those with larger tanks might need to use multiple drop-ins for optimal results, which could increase the usage cost. Despite these minor setbacks, the Camco TST MAX remains a reliable and user-friendly option for maintaining cleanliness and odor control in RV septic systems.

On the downside, while the lavender scent is nice for many, some users may prefer an unscented option or a different fragrance. Also, since one drop-in lasts about 7 days, it means you’ll need to carry enough for longer trips, which might take up some storage space.

This product suits RV owners seeking a straightforward, effective septic tank treatment that balances odor control, waste breakdown, and environmental considerations.
