Product review (2 stars): Wicks not efficient
I purchased this style of wick intentionallyas I thought the open design would allow for better air flow through the wick thus more moisture in the air over a given period of time.  I was wrong.  During the same winter with the same low ambient humidities, the original manufacturer design (which is solid sheets in an accordian design) wicks much more moisture into the air.  I won't buy these again.
