Just got Kirkland 10.0 h/a yesterday. Hearing aids are great, app not so much. Worked fine for 24 hrs now will not connect. Force stopped app, cleared cache, turned BT on and off, still won't connect. I'll try again in the morning when I turn them on again, might connect then. I had high hopes too. **UPDATE I tried everything Sonova recommended and still the APP would not connect. The H/As were still connected to my phone (Samsung S10e) as I could see them in the blue tooth list, stream to them and see the battery charge, only the app failed to connect, even after clearing cache/data/rebooting/. As soon as I uninstalled the app, rebooted the phone, and reinstalled the app it was fine again.. it's been good all day so far, that seems to be the only solution. I give the app a 2 but I'd give the Kirkland 10.0 hearing aids a 5. Again, the hearing aids are great ! I can hear again, and I have 60% loss both ears. The audio is very good, the battery still has 60% after 12 hrs of wear. If you could get the developers to fix the buggy app it would be an outstanding package, and the price is unbeatable.. A hearing center locally was going to charge me over $4800.00 for these very same H/As with the name brand on them. Overall, if I have to reinstall the app now ad then I can live with that for the convenience of hearing again. They're light years better than the one's my dad used to wear.
