I have just bought the fourth replacement cartridge for my Ultra. The adjustable humidity allows me to change with the seasons, that is, air-conditioning dried versus humid spring and fall.

I have used the Cigar Oasis Ultra 2.0 Humidifier for over a year in a 100 cigar capacity humidor. The humidifier itself works as advertised when there is ample supply of moisture in the cartridge.
However, I have been extremely disappointed in the cartridges. First, the humidifier was advertised as having reusable cartridges. There was no mention of how long the cartridges would last. The assumption was, if you used distilled water, which I did, that it would last indefinitely. This is not the case. I called CI Customer support who told me that they are only good for about 8 or 9 refillings, but should last 2-3 months depending on my specific situation. This also is not the case. After about 5 or 6 refillings, the cartridge would not retain water. This occurred for now 4 cartridges. Moreover, I needed to refill the cartridges every 4 or 5 weeks. To try to help this situation, I put an additional, static humidifying unit in the humidifier.
In conclusion, the refill cartridges have been very disappointing and, even with the investment made in the humidifier itself, will probably be replacing it.

I usually buy the Excel refill because it comes already filled, but I bought the Plus refill by mistake and it has to be filled with distilled water. I filled it and it is working just fine. I did get 3 years of use out of the last Excel cartridge and I am hoping for the same out of the Plus refill. Cigar Oasis was a great investment.
