Are the pin tools to open the hearing aid or change out receivers pretty standard sized across brands? It almost looks like a big paper clip could do the trick. I didn’t see any ReSound branded pin openers on eBay but there are other brands, which makes me wonder how differently sized they are.
I’m considering getting a cheap Windows machine for this purpose. I want to upgrade my MacBook someday. (I just found DIY School today btw, someone slipped me a link.)
