Phonak CeruShield Disk Wax Guards for Marvel Hearing aids

The disc actually made a necessary cleaning procedure. Ear wax build up sometimes creates hearing issues and with the disc, it is much easier to do the required steps to making hearing clearer and the Marvel hearing aid sounds clear and more enjoyable.

This item is needed for my Costco brand hearing aid. This is the best price I have found on line.

Yes they are much better. They protect the electronics of the hearing aid better and they last longer than the older units. Surprisingly the are also a bit cheaper than the old Octicon replacements.My audiologist warned me that they were more difficult to remove and replace than the older wax guards. However there are three simple pictures provided with the CeruShields that make the whole operation simple.So don't be put off by what someone might have said to you. First off, my new Phonak Marvels are expensive but much better than my old hearing aids. And secondly even a caveman can replace the wax guards. I've just proven that. My only problem is that the black case the guards come in is so small that it's easy to lose. Perhaps they can make the case a little bulkier.

I have reordered these guards multiple times. Always the correct item, always prompt service.

Is a bit hard sometimes to get new filter to snap on

The Cerushield Disks are exactly the same as the ones I got from the audiologist. It is quick and convenient to get them from this seller.

I use with Kirkland Hearing Aids purchased from CostCo. The Phonak brand is on the label when I purchased but the CeruShield Disks are the same as those I purchase by visiting CostCo. Both are supplied by Sonova AG, Staefa, Switzerland. Took a gamble buying online. Saved myself a 50-mile round trip to visit the CostCo. folks. I have no complaints about CostCo, but I sure like not having to take the trip to buy the supplies when I need them.

Good product
