I also recommended this seller to 3 of my friends who got different styles and loved it! I was kind of skeptical of the price of this item because I bought my wife a competitor, (which I wont mention) model, which worked well but had to replace every year, I found this model to be as good as or better than that model, the left behind alert on my phone works very well, I had some problems getting the unit to beep when I was searching for it, but I realized my app was out of date, after the upgrade from playstore It works great, in the find it mode, it has a loud beep that can even be I have a neuroma in my left foot and typically have trouble even finding the right sneakers that are properly supportive and have a wide toe box. They give enough lift to make your legs look good, but not so much that youre in pain or feeling unsteady on your feet. I just can?t believe my luck right now ???? Everything was packaged very well, and it was super easy to setup. you won?t be disappointed. I would buy one every year if they were still being made. It needs to be completely renamed AND redesigned. Grandma always said if I did not have so much tucked under I might be 510" or 11".
