Comfortable sleep monitor
Really pleased with the monitor. Works really well and is comfortable to wear while asleep. In the morning I have to refresh the Garmin app a few times for the stats to show but that isn’t a problem.

Poor at detecting anf monitoring when a person is actually asleep
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

Sceptical
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

Unreliable, frustrating and not worth the price
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.

I like it
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.

Fine, but check compatibility
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.

Yes, it’s a comfortable arm band, but that’s about it. Sleep tracking is absolutely terrible. It cannot distinguish between times of low activity (such as when you’re reading in bed) and sleep and therefore gives you an incorrectly high sleep score. I bought it because I didn’t want to pay for it & wear my whoop 24/7 anymore, but it is a totally inferior product that is so inaccurate it will do nothing to assist you with training or recovery metrics.

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.

Ich nutze den Garmin Sleepmonitor nun seit einiger Zeit, um meine Erholung genauer zu tracken und möchte hier meine Erfahrungen teilen. Für jeden, der seinen Schlaf optimieren möchte, ist dies eine Überlegung wert.𝗚𝗲𝗻𝗮𝘂𝗶𝗴𝗸𝗲𝗶𝘁 & 𝗠𝗲𝘀𝘀𝘂𝗻𝗴Der größte Vorteil gegenüber meiner Smartwatch am Handgelenk ist die Genauigkeit.Schon die Zeitpunkte für Schlafeintritt und Aufwachen sind bei meinen Aufzeichnungen mit dem Sleepmonitor genauer als mit der Smartwatch. DIe Daten zu den einzelnen Schlafphasen (Tiefschlaf, REM etc.) erscheinen mir plausibel. Als Sportler schätze ich zudem den genauen Blick auf die Herzfrequenzvariabilität (HFV).𝗔𝗸𝗸𝘂𝗹𝗮𝘂𝗳𝘇𝗲𝗶𝘁Laut Garmin beträgt die Akkulaufzeit bis zu 7 Tage. Diesen Wert erreiche ich bei meiner Schlafdauer nicht ganz, ich erreiche Laufzeiten von 5-6 Tagen. Eine eigene Anzeige für den Ladezustand hat der Sleepmonitor nicht, der Wert kann nur über die App eingesehen werden.𝗨𝗻𝘁𝗲𝗿𝘀𝘁ü𝘁𝘇𝘂𝗻𝗴 𝗯𝗲𝗶 𝗱𝗲𝗿 𝗦𝗰𝗵𝗹𝗮𝗳𝘃𝗲𝗿𝗯𝗲𝘀𝘀𝗲𝗿𝘂𝗻𝗴Die Auswertungen in der Garmin Connect App sind sehr detailliert und bieten echten Mehrwert. Ich konnte verschiedene Maßnahmen in meinem Alltag testen, die sich positiv auf meinen ‚Sleepscore‘ ausgewirkt haben. Das hat tatsächlich dazu beigetragen, meine Schlafqualität gezielt zu verbessern.𝗛𝗶𝗻𝘄𝗲𝗶𝘀 𝘇𝘂𝗿 𝗚𝗿öß𝗲Angaben von Garmin::S–M: Für einen Oberarmumfang von 20 bis 29 cmL–XL: Für einen Oberarmumfang von 26 bis 42 cmEin Tipp zur Passform:Mit meinem Umfang von etwas über 26 cm lag ich genau dazwischen und habe die L-XL-Variante gewählt. Sie passt, aber für einen etwas engeren Sitz würde ich mir ein Ersatzband in der kleineren S-M-Variante zulegen.𝗙𝗮𝘇𝗶𝘁Wer seinen Schlaf ernsthaft optimieren möchte und wem die Messung am Handgelenk zu ungenau oder nachts störend ist (wie es bei mir der Fall war), findet hier eine hervorragende Lösung.Eine klare Kaufempfehlung für alle Statistik-Fans und Gesundheitsbewusste!

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

Non riesco a dormire con l’orologio al polso e mi dispiaceva non poter accedere a tutte le metriche relative al sonno di Garmin che influenzano anche tutta una serie di parametri molto utili per l’allenamento, quindi ho comprato questa fascia. È molto comoda e morbida e ci dormo bene e adesso ho piena funzionalità delle metriche Garmin. Ottima!
