I am using this with my Prestige Chalet humidor and a Calibre 3. Started off with the humidifier supplied and found the humidity was sitting up at 75%, put this baby in instead and within 4 hours it had settled at 70%.
It has now been at 70% for nearly 5 days, noticed a reading of 69% but I am happy with this.
Great product and very low maintenance - ideal for a beginner or someone who doesn't have the time to faff.
Looks a bit tacky though - won't mark down on that though because of the excellent functionality.
