I looked at quite a few different ones, and eventually narrowed my search to two scales. Among other things, I wanted one that fed info into a smartphone app for tracking. Also I wanted an app that I could download from the Apple App Store and not an app that I would have to download from the manufacturer's website. (If it's been cleared for the Apple (or Google) App Store, it's probably safe to download.) The Hume and the other scale both did that, and both were about the same price. They also appeared to offer the same information measurement/tracking. It was basically a coin flip. There are probably at least a dozen smart scales on Amazon if anyone wants to dip their toe into the smart scale technology. Prices start under $100.
