Garmin sleep Monitor, Lightweight Smart Band for Tracking Stages, Recovery, Up to 7 Nights Battery Life, S-M

The idea behind this product makes sense. A dedicated sleep band so you don't have to wear your watch to bed. Unfortunately, the execution falls well short of what you'd expect from Garmin at this price point. The most frustrating issue is that it simply fails to detect sleep some nights. You can open the app in the morning and see a full night of heart rate data, proof the band was working and worn correctly, yet no sleep session is recorded. For a product whose entire purpose is sleep tracking, this is a fundamental failure. Syncing is the other persistent problem. Getting the band to talk to the app can take anywhere from 15 to 30 minutes, and sometimes it doesn't happen at all regardless of how many times you try. This is a daily frustration, not an occasional one. On top of this, the number of times I've had to remove and re-add the device entirely because it simply stops working is frankly unbelievable. This is not a minor bug; it's a recurring issue that suggests something is fundamentally wrong with how the device maintains its connection. Garmin clearly didn't put this through sufficient real-world testing before release. These aren't edge cases; they're core functions that don't work reliably. At this price, that's not acceptable. If you're already in the Garmin ecosystem and want to avoid wearing your watch to bed, the appeal is obvious. But until Garmin addresses these reliability issues properly, I can't recommend it.

Updated: device does "settle down" and has actually becone fairly accurate (in line with other industry devices). Convenient as its worn a band. Not a bad device just a little high on the price side. Placeholder review: I'm sceptical. The device still uses the Garmin format of setting your "sleep window".The first night I tried to stick to the "window" to get a base set of data. The device did not record my sleep and wake time at all, I had to set it manually! The data between what I guestimated my actual fall asleep time was and wake time was recorded HRV etc but it feels to user dependent. I can go back at any time and edit the fall asleep and wake times. There is no device recorded start and finish it's bizarre

The monitor is very lightweight and is not uncomfortable to wear, even over extended periods and does not inhibit sleep. So why the 1 star? It does not work. Over 4 consecutive nights, the device only managed to detect and monitor 2 nights' sleep of ~1hr, so results (surprise, surprise!) Poor Sleep, despite me actually getting 8 hrs. It simply fails to accurately detect and monitor when you are actually asleep. Returned and refund requested

It's very good. It works well, it feels well. One star off, as it would not pair. It took me some time to mess around with Bluetooth and the Connect app to make it work. It should have been another star off for a really high price but so far so good. It works well.

Does what it says on the tin, but if you're planning to use this alongside an existing Garmin watch make sure your watch has Body Battery TrueUp which is limited to newer models, or you'll get no stress and body battery data.

É bem confortável pra dormir e não atrapalha o sono igual o relógio. Só a bateria que não aguenta mais que 3 dias. Valeu a pena ter comprado. Tenho todas as métricas em dia com ele

⭐⭐⭐⭐⭐ Präzise Schlafanalyse ohne störendes Handgelenk-Gefühl Ich nutze den Garmin Index Sleep Monitor jetzt seit einiger Zeit in Kombination mit meiner Fenix 8 und bin absolut begeistert von der Genauigkeit und dem Tragekomfort. Das Problem: Ich trage meine Fenix 8 tagsüber extrem gerne, aber nachts hat sie mich am Handgelenk oft gestört, was paradoxerweise mein Schlaftracking verfälscht hat, weil ich unruhiger geschlafen habe. Die Lösung (Mein Setup): Ich lege die Uhr abends ab und ziehe den Sleep Monitor am Oberarm an. Das weiche Band spürt man nach zwei Minuten nicht mehr – kein Vergleich zu einer klobigen Sportuhr. Erkennung & Genauigkeit: Was mich am meisten überrascht hat, ist die Präzision im Vergleich zur reinen Pulsmessung am Handgelenk: Schlafphasen: Die Erkennung von Wachphasen und Tiefschlaf ist deutlich plausibler. Während die Uhr am Handgelenk oft "Wachzeiten" registriert hat, nur weil ich den Arm bewegt habe, filtert der Oberarm-Sensor das viel besser heraus. Nahtlose Integration: Sobald ich morgens die Garmin Connect App öffne, fließen die Daten vom Armband und der Fenix 8 perfekt zusammen. Mein Training Readiness Score und die Body Battery berücksichtigen die präzisen Nachtwerte des Monitors, als hätte ich die Uhr getragen. Zusatzwerte: Die Messung der Hauttemperatur und der Atemfrequenz liefert sehr konstante Werte, was mir hilft, meine Regeneration nach dem Training (ich trainiere viel) besser einzuschätzen. Fazit: Wer eine Fenix oder eine andere große Garmin-Uhr besitzt, aber nachts "frei" sein will, ohne auf die wertvollen Daten zu verzichten, findet hier die perfekte Ergänzung. Die Erkennung am Oberarm ist für mich das Goldstandard-Upgrade zum Handgelenk-Tracking.

This sleep monitor gives you exactly what you need to track your sleep. Way better and way cheaper than the Oura Ring or the Whoop device. You pay one time and there are no subscriptions. Also, the material is very comfortable. I don’t even notice while Im sleeping.

this product is fantastic especially after the disappointment with sleep tracking using my Wellue BP smartwatch, its BP monitor is great BTW. I prefer wearing the Garmin arm cuff to bed than a watch anyway. The sleep chart is definitely accurate in terms of start and end time, I trust the sleep stage times as I can compare these to my Resmed CPAP machine metrics that flow into my myAir app. I'm following CBT-I (Cognitive Behavioral Therapy for Insomnia) as I'm currently sleeping only 4 to 5 hrs a night and want to extend this to 8 hrs. The sleep tracking is extremely helpful for this. Now I have to tell you why I dropped one star. The battery ran dry on me and I had to re-pair. You do this tapping the module 15 times. I must have had to repeat this 20 to 30 times before the module entered pairing mode to reconnect with my phone. I almost gave up their troubleshooting instructions are useless. I have sent Garmin support a feature request, give us a more deterministic way to pair. Initial pairing went smoothly so don't let your battery run dry.

Yo lo compré para tener métricos relacionados con mi sueño y así evaluar que tanto lo requiero para mis entrenamientos de sesiones largas al correr, así puedo ver si descanso suficientes y necesito más o si hay alguna alteración en mi cuerpo, además, la conexión es automática y rápida ya teniendo la aplicación garmin connect
