Hi there, I’m in Perth, Western Australia and found UCan_Hear hearing aid repairer in Shakopee, Minnesota USA.
It was a completely seamless experience. My right Phonak P90 hearing aid was returned with a new battery working again. Postage was high though. Cost of repair was US$104 plus shipping. And shipping from Western Australia was US$50 each way. There are no repairers in Australia.
I’d bought my hearing aids second hand from a US seller in 2022. When the left hearing aid bean wouldn’t charge in 2025 I sent it to Phonak to have a battery replacement. No warranty because bought overseas. Then no replacement because no serial number in their database. It might have been claimed on insurance?
Weirdly the returned left bean has worked well for a whole year. 
Then in February 2026 the other right bean hearing aid completely died. Wouldn’t charge. I contacted UCan_Hear after hearing about them on this forum. He has excellent eBay feedback reviews. I can recommend his services. I felt he definitely earned my trust. I sent my packaged bean, it took no time for the repair and then it was sent back to me. The fixed hearing aid arrived ready to use immediately, all fitting settings as before. I do have an audiologist but did my own fitting. She’s been very helpful when I needed custom molds.
I shall be sending the left hearing aid to UCan_Hear soon because it is only holding about 12 hours charge now. I do top up charge at about mid afternoon to get me through the evening. I also have a pair of Phonak P90 312 replaceable battery hearing aids to use.
And a final bit of good service is that the repaired bean (which wasn’t working at all, so would have been tossed into landfill) has been working well. But it also falls to 8% charge at mid afternoon, very suddenly from 50%, in about 20 minutes. I notified the repairer and he has offered to fix that right hearing aid bean free of charge, when I send both of them. It’s not the cost of repair but the shipping costs that are high.
Still, the alternative was to spend AU$6K on a new pair.
So I am well pleased with this outcome.
I am very happy to recommend this hearing aid service repairer. He communicated well and relies on word of mouth recommendations.
I’m a regular reader of this forum but do not often share. Hope this helps.
Cheers
Anna
