Product review (4 stars): Works good, but not for long.
This wick is nice and thick, made of some sort of paper. It works great for about 2 weeks then I have to start flipping it over every few days because the top will dry out even with a low fan speed. By the time the next one shows up the next month, the old wick is dead and needs to be replaced. If I run my humidifier on High speed the wick will dry out in a day.
If there was a better wick I would buy it. But this is the best we have right now.
