I only used this once last year but I was happy with the performance. This worked to keep the system odor free for the weekend I used it and the clean up and emptying of the system was more pleasant. I do not know for sure that longer term use will be as pleasant, but based on the performance for the one weekend I can state with a lot of confidence that it will work great. I am getting another bottle for this season. Be sure to shake it well before each use.
