Product review (3 stars): They are very easy to trim so I had no problem there
I use these disks in my Vicks vaporizer.  They are larger than the original Vicks  product that came with the vaporizer.
They are very easy to trim so I had no problem there.
The disks are intertwined and with the smaller ones that came with the vaporizer I used a pair.
This box has six sets of intertwined disks (total of 12) so I guess I should separate them.
I had a hard time finding disks that would fit my vaporizer.  I noticed they appear on Amazon website as a suggested product for the Vicks vaporizer even though it is not exact fit.  Maybe I am looking in the wrong places but for the price plus shipping around $25 total it is ridiculously expensive !!!.
If you read this review and have better source please let me know.  There is an other source listed on Amazon with a possible shipping within 30 days  !!!.
