Quick answer
For US shoppers comparing these smart body-fat scales, the current registry lists Etekcity at $70.69 and RENPHO Elis 1 at $19.99. RENPHO is $50.70 lower. Etekcity records 4.7 stars from 347,025 captured reviews; RENPHO records 4.6 stars from 334,483. Manufacturer pages for the two named models list app-connected tracking and 13 body measurements, but the Etekcity registry title says TFT while its current ESF-551 manufacturer page says LED, so verify the exact ASIN and model before relying on display or connectivity claims. Consumer body-composition readings are estimates, not diagnoses. The CDC treats BMI as a screening measure, and published research shows consumer BIA devices can differ from reference methods. No independent Etekcity-versus-RENPHO accuracy test was performed.
RENPHO is $50.70 cheaper; Etekcity has the higher snapshot rating and larger review pool. Verify the Etekcity model/display identity and treat body-composition outputs as estimates.

Start with the price and the exact model
The current US registry lists Etekcity at $70.69 and RENPHO Elis 1 at $19.99. RENPHO is $50.70 lower, so this is not a close price comparison. The live manufacturer pages describe both as app-connected scales that estimate multiple body measurements, but the marketplace records and model pages should still be matched before checkout.
The Etekcity registry title identifies a TFT display, while the current Etekcity ESF-551 manufacturer page describes an extra-large LED display and 13 biometrics. That wording mismatch is a reason to verify the exact ASIN, model number, photos, and package—not a reason to invent a Wi-Fi or 14-metric advantage.
What both products can and cannot tell you
The Etekcity manufacturer page lists 13 biometrics and VeSync app integrations. The RENPHO Elis 1 page also lists 13 body measurements, Bluetooth, unlimited app profiles, and an LED display. Those are manufacturer-described features, not independent proof that the underlying body-fat estimate is accurate for a particular person.
That boundary matters because consumer foot-to-foot BIA devices estimate body composition indirectly. A published comparison of consumer BIA devices with DXA and MRI found device-level differences and cautioned against treating the readings as interchangeable with reference methods; see the peer-reviewed study. No controlled Etekcity-versus-RENPHO test was performed for this page.
Etekcity: choose it for the ecosystem only after identity is clear
Etekcity has the higher captured rating at 4.7 stars and the larger review pool at 347,025. The current manufacturer page lists VeSync, Apple Health, Samsung Health, Google Fit, Fitbit, MyFitnessPal, Apple Watch compatibility, and unlimited users. These are useful reasons to consider the product, but the exact marketplace variation still controls what arrives.
The registry snapshot price is $50.70 above RENPHO. Pay that premium only if the current model, app workflow, display, and integrations solve a real problem for you. A larger review count is marketplace history, not evidence that Etekcity produces a more accurate body-fat percentage.
RENPHO: the value path is straightforward
RENPHO is listed at $19.99 with 4.6 stars from 334,483 captured reviews. Its manufacturer page identifies Bluetooth connectivity, the RENPHO Health app, an LED display, 13 body measurements, a 400-pound range, and three AAA batteries. It is the sensible starting point when the buyer wants app-based trend tracking without paying Etekcity's current premium.
RENPHO is not a clinical shortcut. The manufacturer says the Elis 1 is for daily home use and should not be considered for medical purposes. Follow the current product guidance, and use weight-only mode or professional advice where the manufacturer says body-composition measurement is inappropriate.
Ratings and review volume are context, not a test
Etekcity records 4.7 stars from 347,025 reviews; RENPHO records 4.6 stars from 334,483. Etekcity leads on both rating and review volume in this snapshot, but a 0.1-star difference and a large review pool do not establish calibration, repeatability, or clinical validity.
Read reviews for the exact ASIN and variation. Look for recurring reports about app pairing, battery access, display behavior, platform size, and variation confusion. Do not turn a reviewer saying “accurate” or “consistent” into a universal performance claim.
BMI and body-fat numbers need a health boundary
The CDC explains that BMI is a screening measure, not a direct measure of body fat or a diagnosis. A smart scale's body-fat, muscle, water, or metabolic-age outputs add estimates; they do not replace a physical exam, laboratory result, or validated clinical measurement.
Use the same scale, same conditions, and the manufacturer’s setup instructions if you are tracking a personal trend. Do not make diet, medication, pregnancy, eating-disorder, or other clinical decisions from one home reading. Consult a qualified professional when the stakes are medical.
Alternatives
The Etekcity Upgraded Smart Scale is a lower-priced Etekcity option in the current registry. FITINDEX is another Bluetooth 13-metric format. They are separate alternatives, not silent replacements for either primary ASIN; check the exact model, app, metrics, capacity, price, and return terms.
What this comparison does not establish
No independent test was performed for body-fat accuracy, repeatability, calibration, app reliability, privacy, display readability, battery life, or medical suitability. The recommendation is limited to current registry facts plus linked manufacturer, CDC, and peer-reviewed sources.
Bottom line: choose RENPHO when the $50.70 saving and Bluetooth app workflow fit. Choose Etekcity when its exact model identity, VeSync ecosystem, and higher current marketplace signal justify the premium. Confirm the live ASIN and treat body-composition outputs as estimates.

Frequently Asked Questions
Which is better, Etekcity or RENPHO?
RENPHO is the value choice because it is $50.70 lower in the current registry. Etekcity is the scoped choice when its exact model, VeSync workflow, and higher marketplace signal justify the premium. Neither is an independent accuracy winner.
Which scale is cheaper?
RENPHO Elis 1 is listed at $19.99 versus $70.69 for Etekcity in the current US registry snapshot. Check the exact variation and delivered price before ordering.
Do these scales accurately measure body fat?
This page does not establish that. Both manufacturer pages list body-composition estimates, but no independent Etekcity-versus-RENPHO accuracy or calibration test was performed. Consumer BIA devices can differ from reference methods.
Does Etekcity use Wi-Fi?
Do not carry the retired article’s Wi-Fi claim forward. The current Etekcity manufacturer page used here describes VeSync app integrations, while the registry title and manufacturer page use different display wording. Verify connectivity for the exact ASIN and model.
Is BMI a diagnosis?
No. The CDC describes BMI as a screening measure and says it should be considered with other health information. Do not use a scale reading as a diagnosis or substitute for professional advice.
Did Mubboo test either scale?
No. This comparison uses current registry data, exact listing records, manufacturer documentation, CDC guidance, and a linked study. It does not include physical, calibration, accuracy, privacy, or medical testing.
How we checked it: Product facts use the current US registry and exact Amazon records. Feature and safety boundaries are checked against the Etekcity ESF-551 manufacturer page, RENPHO Elis 1 manufacturer page, the CDC BMI explainer, and a peer-reviewed BIA comparison. Prices and availability are dated snapshots, not promises.
