I just got my KS7 in January also, so far it’s better than anything I’ve had before. This is the problem I had: While changing the battery on a gravel driveway, I dropped the aide and lost it. I searched for 4 days. I looked for a finder feature, an app, anything. I found the app for model KS6 that has a finder feature, but that was made by a different company. Rexton makes the KS7 and there is no finder, no special app. Maybe leaving out the special features is why they got the bid! The finder feature is so important! Now I have to use up my one free replacement offer, when I know it’s there somewhere. Also, this ends up costing them more money in the end.
