Choose if	You want a Wi-Fi scale that syncs weight and body composition to Garmin Connect and can serve up to 16 people.	You want a low-cost scale that tracks weight trends and sends body readings to the Wyze app.
Main trade-off	It costs $199.99, Garmin publishes no accuracy figure for the body composition readings, and every extra user needs a Garmin Connect account.	Wyze gives no accuracy figure that names the Scale X, and only weight and body fat show on the scale while the app holds the rest.
Key specifications	Body composition method: Bioelectrical impedance. A small current runs from one foot through the body to the other foot, and Garmin lists no handle or hand electrodes. The pages checked give no frequency or electrode count. It reports body mass index, body fat %, body water %, skeletal muscle mass and bone mass, plus a 30-day weight trend. Garmin says bone mass is calculated from your age and lean body mass Weighing: Units: pounds, kilograms or stones and pounds, set with a switch on the underside. Maximum load 400 lb (181.4 kg). The pages checked give no display step or weight tolerance Profile inputs and modes: Uses date of birth, gender, height and activity level from your Garmin Connect profile. An activity class of 8 to 10 turns on Athlete Mode, which Garmin's FAQ names when body fat reads lower than expected. With socks on, the scale records only weight and BMI. A weight-only option turns off the other body composition data Users: Up to 16 people. The person who set up the scale invites up to 15 others in Garmin Connect. Each needs a Garmin Connect account and a connection to that person. Guest data isn't stored or synced. The scale tells users apart by weight and how often each person weighs in, so similar users can be mixed up Connectivity and app: Wi-Fi (2.4 GHz) syncs readings to Garmin Connect, and the scale stores up to seven networks. Garmin's spec also lists Bluetooth LE and ANT. Setup and settings are in the Garmin Connect app. The pages checked give no minimum phone operating system Battery: Four AAA alkaline batteries, included. Garmin says they last up to 9 months and tells you to use 1.5 V cells Display: A high-resolution color display that steps through your readings every few seconds, plus a weather widget that needs Wi-Fi. Garmin doesn't state its size or resolution In the box: Index S2, four AAA batteries, four carpet feet and documentation	Body composition method: Bioelectrical impedance through 4 electrodes in the glass surface. The Wyze app shows 13 metrics: weight, body fat %, heart rate, lean body mass, BMI, muscle mass, muscle mass %, visceral fat, basal metabolic rate, bone mass, metabolic age, protein and body water %. Only weight and body fat show on the scale Weighing: Four independent leg sensors. Range 11 to 400 lb (5 to 180 kg). Units: lb and kg Heart rate: Measured in the Wyze app in under 10 seconds, according to Wyze. The scale's display shows only weight and body fat Users, ages and modes: Up to 8 users, told apart by weight: they must differ by more than 13.2 lb with the app closed, or 6.6 lb with it open. Body composition appears for ages 10 to 100. Baby, pet, luggage and pregnancy modes, plus a weight-only mode that switches the current off Connectivity and app: Bluetooth 5.0 (BLE), with a range of up to 32 ft in Wyze's testing. The scale stores readings and syncs when you open the Wyze app. Needs iOS 12 or Android 7.0 or later, and syncs with Apple Health, Fitbit and Health Connect. Wyze's spec list names no other connection Battery: Four 1.5 V AAA batteries, included. Wyze says up to 22 months of battery life Display and operating range: LED display for weight and body fat. Operating temperature 41°F to 104°F (5°C to 40°C), storage -4°F to 131°F Use guidance: Bare feet on both electrodes for body composition. With socks or shoes on, the scale measures weight only. Damp feet are fine, but wet feet may affect accuracy. Wyze says carpets and rugs can affect calibration In the box: Wyze Scale X, four AAA batteries and a quick start guide
Exact variant	Index S2 Smart Scale, black (010-02294-02, also sold in white), Wi-Fi 2.4 GHz, four AAA batteries included	Wyze Scale X, black or white, Classic or Butterfly sensor pattern (same price), four AAA batteries included
Dimensions	12.6 x 12.2 x 1.1 in (320 x 310 x 28 mm) and 4.4 lb (2.0 kg), per the specs tab of Garmin's product page. The maximum load is 400 lb (181.4 kg).	11.8 x 11.8 x 1.18 in and 3.96 lb (1.80 kg), per Wyze's tech specs and its comparison table.
Installation	No installation beyond setup. You pair the scale through the Garmin Connect app and connect it to a compatible Wi-Fi router. Garmin says you need both before you can use all its features. Garmin lists a 2.4 GHz Wi-Fi radio. The four AAA batteries are in the box, and so are four carpet feet for carpeted floors. Garmin recommends a hard, flat floor for the most accurate weight.	No installation. Put the scale on a hard, flat floor, since Wyze says carpet affects calibration. Pair it in the Wyze app over Bluetooth, then enter your year of birth, height and other details. Stand on it with bare feet. Four AAA batteries are included.
Materials	A glass surface, per Garmin's manual and support FAQ. Garmin says wearing shoes or heels can damage the glass. The product page offers black and white designs. Other materials are not stated by the manufacturer.	Tempered glass with an ITO (indium tin oxide) coating. Wyze describes the glass surface as the electrodes. It lists an IPX3 water rating and names no frame or base material.
Warranty	One year from the date of purchase, per Garmin's Consumer Limited Warranty. The terms, revised Dec 30, 2025, cover Garmin's non-aviation products and don't name the Index S2. Garmin chooses whether to repair it, replace it with a new or Garmin Recertified device, or refund the purchase price. The warranty excludes cosmetic damage, batteries unless a defect damaged the product, and damage from accident, abuse, misuse or water. You pay shipping to Garmin. A repaired or replacement device is covered for 90 days or the rest of the original year, whichever is longer. In the US, it covers only devices bought from Garmin or an authorized US reseller.	18 months when you buy from Wyze on or after Jan 1, 2026, and 1 year when you buy from an authorized retailer. Those terms come from Wyze's policy effective June 12, 2026. The product page's spec list still says 1-year, while its wyze.com benefits box says 18 months. Wyze replaces the scale or refunds the purchase at its choice. Misuse, modification, attempted repairs and unauthorized retailers aren't covered, and you need proof of purchase.
Returns	30 days from receipt of a Garmin.com order, per Garmin's shipping and returns page. The scale must be in its original condition, and you start the return online with a return request. Garmin says opened software, downloadable items and custom products can't be refunded. The page doesn't say who pays return shipping. Bought from another store, the scale goes back to that store under its own policy, and Garmin says restocking fees may apply.	30 days from the purchase date, only for scales bought on wyze.com or in the Wyze app. You start the return in Wyze's return portal and Wyze sends a prepaid label. The scale must come back in original condition with its accessories and packaging. Wyze refunds the price and sales tax to your payment method, as store credit or on a gift card, at its choice. It doesn't refund shipping and handling. Purchases made during special sale events may be non-returnable.
Unresolved questions	Any accuracy figure or DEXA comparison for the Index S2. Garmin gives none on the pages checked, and a Europe PMC search on Oct 24, 2026 found no study that validated it The data behind Garmin's claim that its readings compare favorably with DEXA, since it comes from a forum reply that names no study or figure The frequency, electrodes and equations behind the readings, which Garmin doesn't publish Whether the weight-only option stops the current Whether the limit is 16 people in total or 16 besides the person who set up the scale, since Garmin words it both ways The weight display step, a weight tolerance and the display size and resolution What replacement AAA batteries cost, since Garmin doesn't price them Which phone operating system versions Garmin Connect needs for setup Who pays return shipping on a Garmin.com return	Accuracy of the Scale X's weight and body composition readings: Wyze gives no figure, and no study naming the Scale X was found Which Wyze Scale model the 2023 study tested Whether the Wyze app or any scale feature ever needs a paid plan What replacement AAA batteries cost, since Wyze doesn't price them Shipping cost for a single scale
