Phonak CeruShield Wax Guard Disks for Marvel, Paradise. 5 Pack

Works great

Second time ordered from this seller. Excellent turn-around and fair price.

Same item that was given to me at audiologist office. Works very well. No issues.

First, you get five (5) disks and each disk has eight (8) wax filters. So you get a total of 40 wax filters. If you change the wax filter in your pair of hearing aids once a month (recommended by most), you have enough to last you for 20 months. That's a great deal for $13 (price when purchased in February, 2024).The disk is an authentic Cerushield product.In the picture of the disassembled disk, I have used two (2) filters (the two on the inner ring) and have six (6) remaining (the six on the outer ring.In the wells circled with yellow, I have deposited an old shield in the inner ring (using the well labeled "1" on the cover) and used the filter that was in the corresponding (now empty) well (using the well labeled "2" on the cover).In the wells circled with orange, I still have a new shield in the outer ring and will deposit my old one in the inner ring.The instructions for using the disk are printed on the inside of the case so it should be pretty clear. Simply put, when there are no wax guards left in any of the wells labeled "1" as you rotate the disk, it's time to throw the disk away and get the next one.NOTE: These fit the Phonak Marvel and Paradise hearing aids and the Costco Kirkland Signature 9 and Costco Kirkland Signature 10 hearing aids. They do not fit other Phonak hearing aids. For those, you need the Cerustop wax shields that also fit other manufacturers such as Unitron, Widex and Resound (also Jabra).I own Costco KS 9 and Costco KS 10 hearing aids as well as the new Jabra Enhance Pro 20.

perfect for Phonak hearing aids, easy to use

Have used these for 4 years now.

They are the original product, just a lower cost.

Everybody's a little bit different, but I find that I need to replace these guards about every 10 days before the quality of amplification goes down on my Phonak hearing aids. It's a very simple and easy way to keep your hearing aids working at the best level.
