Index S2 Smart Scale, measure weight & body composition, BMI, weight trend, body fat percentage, muscle & bone mass, built in wifi, pair with Garmin Connect, up to 16 users, Black

Excellent scales with eazy connections to garmin gear and the rather incredible app. I do trust the reading. Bone mass, muscle, and water weight are consistant. Valuable tool for health. I love the appearance and it is made from high grade materials. There is display so you know when the weigh in is complete. You can set up a number of profiles too.

What can I say, its Garmin.... easy to set up and sync, accurate and look lovely. If you have a Garmin wrist watch.. get these, its worth it.

With the Garmin Index S2 Smart Scale, one steps onto a platform that merges tech finesse with pared-back aesthetics. Visually, it's a minimalist's dream—no unnecessary frills or garish designs to clutter your contemplative mornings. Let's dive right into the bright, readable screen that's akin to a lighthouse guiding foggy-eyed wanderers towards a healthier lifestyle. No squinting, no guessing; it delivers your data with clarity and assurance. And talk about being a team player! The effortless integration with Garmin Connect is the epitome of streamlined convenience. Your metrics flow smoothly from scale to app, almost as if they're commuting on a Swiss train—always on time, always reliable. The WiFi integration is equally steadfast, eliminating the fuss of constant troubleshooting or reconnecting. But not all is rosy in this domestic paradise. The glaring omission of a resting heart rate measurement is akin to a Shakespearean tragedy missing its third act. How can a device so accomplished in other metrics overlook this vital sign? A baffling mystery, indeed. The scale's ‘tap to wake’ feature and sluggish post-weigh response time offer another set of head-scratchers. One might liken it to waiting for a sommelier to choose the perfect wine—except in this case, you're not waiting for a vintage Bordeaux but rather a simple acknowledgment of your existence. All told, the Garmin Index S2 Smart Scale masterfully balances its virtues and shortcomings. If your expectations are aligned accordingly, it's a worthy addition to your health and wellness arsenal. However, be prepared to overlook its small but discernible flaws—like a superb novel with a few errant typos. Worth the read, but not quite a modern classic.

After several weeks of daily use, I can confirm that the Garmin Index S2 fully meets the expectations of an active user who wants to track body metrics accurately and consistently. Straight out of the box, the product feels premium: clean design, excellent build quality, and a bright color display that remains readable even in low-light environments. Setup is simple and quick, with seamless Wi-Fi configuration. Unlike many other smart scales, the Index S2 uploads data directly to Garmin Connect without requiring you to open the app after each weigh-in. This is a real plus for those who value effortless tracking. In terms of accuracy, the weight measurement is extremely reliable. I compared it with professional-grade scales and found only minimal variation. As for the body composition metrics (body fat, muscle mass, water percentage, bone mass), it’s important to keep in mind that they are based on bioelectrical impedance. Like any impedance-based scale, the absolute numbers should be interpreted with caution. However, they are very useful to track your trends over time, as long as your measurement conditions are consistent (same time of day, hydration level, food intake, etc.). The real strength of this device lies in its seamless integration with the Garmin ecosystem. All your metrics are consolidated alongside your activity, heart rate, cycling data, and sleep stats. This gives you a complete overview of your health and fitness. You can monitor your basal metabolic rate trends, correlate your weight with heart rate patterns, and track your recovery over the long term—something few smart scales on the market can offer at this level of consistency. The Index S2 supports multiple user profiles. It automatically recognizes frequent users but also allows manual selection if necessary. This makes it suitable for families or shared environments where several people want to track their own stats independently. In terms of reliability, I’ve experienced no connectivity issues, no sync failures, and no crashes. Firmware updates happen smoothly, and the product feels stable and trustworthy in the long run. If I had to mention one downside, it would be the price. It is higher than some competitors offering similar standalone features (such as Withings or Xiaomi). However, if you are already a Garmin user, this is the only scale that offers full integration and makes your fitness tracking complete. In summary, the Garmin Index S2 is a well-designed, reliable smart scale for users who take their health and performance tracking seriously. I highly recommend it to anyone looking to centralize their fitness data within the Garmin Connect ecosystem.

Had high hopes for this since I have several Garmin devices for running and cycling and they are excellent. All I wanted was to be able to feed weight and body composition data directly into my Garmin Connect account so all my data is in one place. That and allow the rest of my family to do the same. On the plus side the scale is a beautiful object and looks great on the bathroom floor. Apart from that it proved to be useless and I returned it. Initial setup is tricky and my Garmin Connect app couldn't find the device until I took my Forerunner out of Bluetooth range. To get to that point I still had to call Garmin tech support and wrestle with it while I had them on the line. Eventually we succeeded in getting Connect to add the scale. Accuracy. Weight seems to be measured in line with what I expected from my mechanical Salter scale but the other metrics vary wildly from reading to reading. BF% can vary massively in consecutive readings. Even bone mass changes from reading to reading which seems pretty unlikely. The problem is obviously that metrics like BF% and Lean Muscle Mass are being calculated by algorithms based on the electrical impedance data and other information and parameters that you set in your profile. Since the electrical impedance is only being measured through your lower body (there are no hand contact points) it has to extrapolate from that. One of the parameters in Garmin Connect that you need to set is your Activity Level from 1-10 (10 being the most active - 15 hours+ per week of training). Presumably this is feeding some kind of assumption about your upper body muscle mass into the algorithm because making changes to this can massively impact the BF% you get - if you increase your Activity Level then your BF% goes down. Even after adjusting the activity level my experience was that my BF% varied by as much as 5 percentage points from reading to reading which I just don't think is credible. Additional Users. The ability to add other family members as users who could then sync the scale to their own Garmin Connect accounts was a significant reason I bought the scale. Sadly no matter what I did I could no make this work. I invited my wife to become a user which she did. I weigh 75Kg and she weighs 41Kg so there's hardly going to be much mistake between us but no dice. If I stepped on the scale the expected option to choose between us appeared (tap your foot on the scale to cycle through the users). If she stepped on the scale then no such option appeared and she was only recognised as a 'guest user' and no data is kept. We tried everything to overcome this but after multiple resets, deleting her and reinviting her, we couldn't make the scale see her. The nice ability to sync readings with all my own fitness data via Garmin Connect is hardly worth having if the data itself is suspect and my family can't use it as well. Certainly not worth paying £130 for. I am far from alone in having these problems. Troubleshooting this I found a wealth of comments from people with similar issues in online forums devoted to Garmin products. My assessment of it is that the concept is great but there are significant software and probably even firmware issues that need to be resolved by Garmin before this is anything more than a shiny bathroom ornament. Personally I'm going back to my Salter and manually entering my weight readings to Garmin Connect. I'll just have to use the mirror to guess my BF%.

I'm building up a nice portfolio of scales right now, and this one seems to be the better one of the lot. I got this because of two reasons, the first, a message popped up in my Garmin Connect about the S2 scales, I didn't even know that this existed until then, but secondly when I did some research it actually works up to 28 stone. Yeah OK, I have put on some timber recently, and the original smart scale that I have, an expensive Omron Viva one only works up to 23 stone 8 pounds. I'm a little over that (not much) but then the Omron stops working and says "Err" (go away fatty) This Garmin one welcomes you with open arms and step on chunk we'll sort it out. Its pretty good because it connects to WiFi rather than a Bluetooth connection to your phone, meaning that the phone doesn't need the phones Bluetooth on or for it to be close by, as long as you are in WiFi connectivity then it will work. Initial setup required connection to the phone but it was pretty quick to set up and not much hassle. Straight into my Garmin Connect account and it was ready to go. The way it detects the user is also handy, if you have multiple users, it saves you sending the wrong weight to the wrong person, I thought that was handy, though I am the only user of it, but I can see where that would be of benefit. Garmin Connect has all the usual connectivity too, MyFitnessPal, Google fit and Google health connect all work fine collecting the data. Impressed with this, and might not even go back to the Viva now I am under its weight limit.

Gives accurate readings daily, uploads straight onto Garmin App and remembers previous days & data.

This is a decent product overall, but it's overpriced (bearing in mind you can get something very similar for a fraction of the cost that isn't stamped with the Garmin brand). It's also glitchy... Initial set-up was sorted after a bit of faff, and it does seem to distinguish properly between my wife and I when we step on it. But multiple times each week it seems, you step on it, but instead of weighing you, it wants to sync. So you have to step off and wait a few mins while it gets ready to weigh you. Quite why it doesn't sync properly after each weigh-in, I don't know, but it's annoying. But, all that said, it does seem to work well... can't be 100% sure it's pinpoint accurate, and my weight does seem to yo-yo a fair bit, but that might be the nature of it anyhow. Would I recommend? Well, if you have the Garmin ecosystem, it might be worth it. That said, I'd be tempted to get something by Renpho (for example) and simply input my weight to the app each day instead.
