I have used this as well as other RV treatments, and this one is deffinatly the best. All the other brands I have tried will knock out the odor for about 3-4 days, but this one is good untill the next time you empty your black water tank. If you are going to be using your toilet heavy for a large group or somthing you may need two packets, otherwise one will do just fine.
