they work if you get a good one..50-50 gamble
Review by Michelleon 12/20/14
In the last year it seems the quality has gone way down. Sometimes you can open it up and look at it and notice right away how thin the filter/filler is..it looks more like mesh and is holey and not thick as when you get a good one. Then when you use them, you are lucky if they last 2 days. it is to the point a store not to far from my home, actually allows you to return them (if purchased there) because they have had so many recent complaints and they give you new one..which again is a gamble. I am so frustrated. They used to be good and last, now they are not at all reliable. Not only that, you waste alot of liquid filling em to try to get them to work. It is as if they want you to purchase more liquid, or upgrade. I am currently trying out different brands, as much as I prefer the Volcano.
