My experience with KS10:
Previously had Marvels, occasional weirdness with charging as others have reported. Happened about three times per year, switching aid off and on again was an easy solution.
My wife and I each managed to lose one aid during a fire evac, so we purchased KS10s. Both have experienced charging-light weirdness. It’s different and more frequent than my Marvels. Happens about once a week for me, once a month for her. Example 1. put aids in charger overnight, bluetooth aid blinking red in the morning, but app shows fully charged and aid works normally. Example 2. aid gives low bat warning, put aid in charger, it blinks green. Strange, but no big deal.
However, we also both have issues after switching to new phones that use Android 12. The aid designed for bluetooth has excessive battery use, such that in my case that aid will warn of low battery about 5pm like clockwork. A short recharge is a sufficient workaround but a PITA. My wife’s aid is doing the same thing, but since she uses them for fewer hours she doesn’t need a recharge. Several others here have reported the exact same issue, and that the solution is to install Android 13. That should be available for our phones in a couple months.
My conclusion and guess: I’m mostly happy with the KS10s and have worked around the issues. But many people could be expected instead to take advantage of Costco’s generous service and return policies, and the result has probably been thousands of returns and replacements. If that’s the case then it’s likely that Costco is tired of it.
