Signia HF4 PRO Wax Filter, Blue for Left Ear

Excellent Wax Filter for Left Hearing Aids.

I love the fact that whenever my form fitted rear aid's filter is clogged (I have very waxy ears!), I can charge it, lickety split! So easy to get the old filter out and the new one in!Follow the directions!

Battery for hearing aid.

Brought these for my dads hearing aide. Red and blue, one for the right and the other for the left hearing aide. Glad I found them in Amazon.

Product came quickly and was what was advertised

Works well.

I tried to replace the filters with the stick provided as a tool. I used the threaded side stick of the stick--which are almost impossible to see without a magnifying glass--to remove the filter. I had to force it into the old filter, which I removed, then used the opposite side to insert the new filter. The threaded side broke. By the way: the instructional pictures indicate the threaded side, but the picture is so small...I bought the red filters for the other ear--and the stick broke before I was able to remove the old filter. Now I can't use any of the filter because both sticks are broken. If Siemens will make good on them, I'll change my review.
