Bests & Worsts Reviews from Amazon

Pros: - Quick and easy setup - Bluetooth connectivity is pretty good. Only failed once on me so far. - Pretty legible display, though numbers after decimal perhaps a little too small for people with poor eyesight. Cons: - Companion iOS app needs to be on and nearby to get data besides weight and to import to iOS Health. - iOS app is not very good. Clearly an afterthought for Eufy. And it's not really designed for scale use: the graphs and tracking metrics aren't really designed to be useful to user. I just use my iOS Health app to visualize stuff. ** Body Fat: This is most important to me. I realize that body fat readings aren't very accurate short of a professional scan. But I got this mainly to track progress and changes. Eufy claims they are using electrical currents to read body, but the body fat readings seem to be exactly proportional to weight. For example, my weight today is the same as one month ago and my body fat reads exactly the same to the tenth percent. Is that likely? It is very obvious that most of the work is being done by some algorithm rather than an electrical-current scan. You go for a run and go to the bathroom -- easy to lose a few water-weight pounds in a day. But the scale claims that as I lost 3 pounds over the day, I also dropped 1.3% body fat. That body fat change seems highly unlikely. Again, most of the work obviously comes from a calculation rather than an electrical scan. For that reason, I don't really trust that it'll recognize when I'm building muscle (since muscle and fat weigh very differently). I will change my rating in case Eufy pushes out some firmware update that makes the body fat readings more meaningful. For now, they seem made up -- based on weight (and other variables), rather than actual electrical currents.
