stickman, I get a good amount of phone calls from people who are looking to improve the humidification in the Tower humidors. The Accumonitor Jr would work a lot better then the Cigar Oasis. The JR will have much more water capacity, and the output of the fans is much more powerful. However, please consider the standard Accumonitor. Those Towers usually require several canisters placed at different levels to even off the humidity. Also, with the extra circulation fans and the timer feature, the standard Accumonitor will do a much better job.
