First time. Used with Big Brandname sachets and small humidifiers in large jars. Everything runs flawlessly. This is good because each package is individually wrapped. One major brand packs 5 or 10 in plastic wrap and once the pack is opened all the packs start to do their job/eventually wear out. This includes paper squares with a coating that will rub off and let you know they are used up/no longer effective. My little humidifiers do that for me, and the pouches get dry and crumbly when they're done, so you can tell just by holding them. Conclusion: They are at least as effective as Big Brand. Custom packaging outperforms bulk branded packaging. They are slightly cheaper than the big brand. Tip: Buy small humidifiers for your jars. They're cheap enough that you can easily put 1 in each jar.
