I rarely write reviews, but I had to for this! I knew my hearing aids were somewhere in my house, because they synched to my phone. But, the hearing aid finder app that came with them was so bad, it could not even tell me what floor they were on, with a lot of false hope. I looked with that for 2-3 hours. I tried several other apps to help, for another full hour, with no luck, and more false hope. I very nearly gave up. THEN, I saw and tried Wunderfind, and it immediately, and so much more easily, began honing in on them, including floor level location! WOW! So easy!!! It said my hearing aids were inside my car door, which could not be. I had already looked under the car just below where it said they were, and thought nothing there. Then, I realized I had ignored a garbaged up old napkin under my car, Wunderfind said it was in that!!! I then looked in it and realized I had put them in that old napkin that I had thrown on the garage floor clearing out my car to find them. Then, Wunderfind said they were in it. I almost didn’t even look, thinking something was wrong, but there they were!!! I would have for sure thrown that napkin in the garbage, and never seen the hearing aids again. EXCEPT!!! Wunderfind found them!!! THANK YOU!!!
