I have seen and used the Kinnaird Kanister Moisture Control System in both Ross bags and Banatyne hide/synthetic bags and am extremely impressed with its effectiveness at eliminating virtually any moisture build up in the bags, chanter or drones. The system is very easy to install and maintain as well. I am not a particularly wet blower,but I have engaged in extensive playing sessions; up to 30 minutes at a time and up to 2 plus hours over the course of a day, and at the end my system is still dry. Very impressed!
