Product review (5 stars): Perfect Fit Wick
These are very hard to find in the stores.  I bought this machine several years ago at the local Giganto Hardware Store.  They carry some off the wall replacement that you have to custom cut and it costs even more than I paid for this one.  I opened the box and inserted the Wick which fit perfect right out of the box.  These are the best wicks and last all season at my house.  I will never buy another replacement off brand wick again.  Thanks Amazon, my wife's sinuses thank you as well.
