Dropping to 4/5 stars because the weight can fluctuate a pound. My cheaper scale by Renpho can deliver steady weight readings, why can’t this $400 scale?Accuracy: 5/5This scale agrees with the professional inbody scans I've had at my local nutrishop.Robustness: 4/5The casing feels like a cheap plastic, and the LED screen looks dated.App: 5/5Easy to use. When people say it's hard to sync. Make sure you click "Start in bodyscan" through the app before you step on the scale. The scale has to be initially off before you click "start inbody scan" in the app or else it won't sync.Cons: - I wish it had segmental analysis but InBody probably wants people to purchase and use there professional equipment so don't offer the segmental analysis, professional reports and viseral reading on this scale.- Like people have mentioned the weight does vary. I usually way myself about 6 times. And the last 3 times are constant for whatever reason. Also, make sure you follow the recommendations that are in the instructions; posture, test in the morning after going to the bathroom before eating(and only at this time).Overall this scale is the: only BCA scale on the market worth the money. I tried the competitor "FitIndex" BCA scale and it was garbage.
