## Questions & Answers

**Q: Is the body fat reading on this scale almost same as dexa scan or are the reading off by alot? And is the weight accurate on this scale or way off?**
A: Ok here’s what I’ve experienced within the last two days. I’ve been in bootcamp now for 6 weeks and every week we get measured with the inbody composition scales that costs around $6000. I wanted something for home but the inbody home version is $350. I didn’t want to spend more than $100 so saw this one. The fat preventage, water weight percentage and muscle mass are way off. Example my my fat percentage in the inbody is 16.7% vs 23.4 with this and that’s using the athlete mode. If I use standard mode it’s 28%. That’s insane!

**Q: can you see the weight in kilo gram or only in libs?**
A: You can switch Weight Units to KG, LB,  or ST: LB in the app.  Also for height you have the option of CM and INCH

**Q: Battery stopped charging; have only been able to charge it once. Doesn’t come with a charge cable or instructions; how does one replace the batteries?**
A: It’s supposed to have a usb cable for charging, but it will not have a plug, you’ll need to connect it to an adapter like for an older iPhone then plug into a wall, or a USB powered port somewhere.

**Q: Pesa en kilogramos?**
A: si kg y lb

### ⭐⭐⭐⭐⭐ Review
*by M***B on 23 December 2025*

After two years of searching for an accurate smart scale and cycling through brands like Etekcity and Xiaomi, I have finally found a device that delivers professional-grade results: the RunSTAR. As someone who has consistently tracked body composition using both various consumer brands and professional InBody machines, my assessment comes from a place of long-term comparison and direct experience with high-end clinical equipment. I know what precision looks like because I have the data to back it up. The evidence for this scale is clear: the RunSTAR's metrics align almost exactly with my clinical InBody readings. Beyond the accuracy, the utility is impressive, offering three distinct report layouts that allow you to analyze your data in the way that best fits your specific fitness goals. The consistency between this device and a multi-thousand dollar clinical scale is remarkable. It is disheartening to see "scam" reviews circulating on social media that mislead people who are genuinely trying to improve their health. I understand the frustration of spending money on gadgets that don't work, but I assure you that this product is legitimate. Don't let a viral video rob you of a tool that actually delivers. This scale provides the peace of mind, ease of use, and clarity necessary to stay motivated on your journey.
