RunStar 8E Body Fat Scale
An 8-electrode smart scale that estimates roughly 28 body-composition metrics with segmental analysis, at a value price.
Body-composition scales are the cheapest way to track a trend that matters more than raw weight: how much of you is muscle versus fat, and whether it is moving the right direction. The RunStar 8E is the value pick, an 8-electrode scale that reads about 28 metrics for around $100.

Body-composition scales are the cheapest way to track a trend that matters more than raw weight: how much of you is muscle versus fat, and whether it is moving the right direction. The RunStar 8E is the value pick, an 8-electrode scale that reads about 28 metrics for around $100.
The 8E uses eight electrodes (hands and feet) rather than the four-electrode, feet-only design of budget scales, which lets it estimate segmental composition (arms, legs, trunk separately) instead of a single whole-body number. It reports roughly 28 metrics including body fat, muscle mass, water, bone mass, visceral fat, and BMI, syncing to a companion app for trends.
The honest caveat applies to every consumer BIA scale, not just this one: bioelectrical impedance estimates composition by sending a tiny current through the body, and absolute accuracy drifts with hydration, time of day, and recent food or exercise. The number to trust is the trend under consistent conditions (same time, same state), not any single reading against a DEXA scan.
At $100 the 8E sits well below premium body-comp devices while offering the segmental, 8-electrode approach that cheaper scales skip. It is a tracking tool, not a diagnostic.
Anyone who wants an affordable way to track body-composition trends at home with segmental (per-limb) readings, and understands to watch the trend rather than any single number.
You need research-grade absolute accuracy (that is a DEXA scan, not a home scale), or you only care about weight, in which case a $30 basic scale is enough.

RunStar 8E Body Fat Scale - buyer FAQ
How accurate are body fat scales like the RunStar 8E?
Bioelectrical impedance scales estimate composition by passing a tiny current through the body, and absolute accuracy shifts with hydration, time of day, and recent meals or exercise. The 8-electrode design improves on feet-only scales, but you should track the trend under consistent conditions rather than trust a single reading. Verified July 2026.
What does the RunStar 8E measure?
It reports roughly 28 metrics, including body fat percentage, muscle mass, body water, visceral fat, bone mass, and BMI, with segmental (arms, legs, trunk) breakdowns thanks to its 8 electrodes. Readings sync to a companion app so you can watch trends over time.
How much is the RunStar 8E scale?
The 8E is $100, recently down from $130, verified on runstar.com in July 2026, with free shipping. RunStar's lower-tier scales run $28 to $60 if you want basic weight or four-electrode composition at a lower price.
Is an 8-electrode scale worth it over a cheaper one?
The benefit is segmental analysis: eight electrodes measure your arms, legs, and trunk separately rather than giving one whole-body estimate from your feet. If you want per-limb muscle and fat trends, it is worth the step up; if you only track weight, a basic scale is fine.
