Customers are mixed about the performance of the wearable computer. Some mention it makes them stay more active and motivated, and is really helpful to gain more understanding and self-compassion. The tracking feature has helped tremendously in mindfulness of their habits. However, others say that it stopped working after only 26 months, which is too short for a device that cost $250. They also say that the product fails miserably in its most primary function, and that it constantly disconnects from the phone.

Customers have mixed opinions about the battery life of the wearable computer. Some mention that the battery seems excellent and runs for about 8 days before it needs a charge, while others say that it drains really quickly. The battery doesn't last 6 days if you exercise or sleep with the watch, and it will just die. Some say that the 250 steps-per-hour tracking does not refresh daily, and that the watch tends to run out fairly quickly.

Cons: I wish it had better looking clock designs
Doesn’t wake up when I tap on it or turn my wrist. I need to press the side button, it’s a little bit annoying.
For the weights or walking on the tracking pad I need to select the workout modes manually
The only reason I didn't give it five stars is the reliability (or lack thereof) of the charging cable. It magnetically couples to the back of the watch (which I like) using four spring-loaded pogo pins to make the electrical connections. I'm on my third cable; the first two were compromised when one of the springs failed. This causes the po to not go and the watch to not charge. You'll want to keep a spare in a drawer so you're not without a watch while you wait for the inevitable replacement to arrive. The good news is that the replacement charging cables are not expensive--at least relative to the watch itself.
---------------------------------------------------------------------------------------
Probably want to select reviews based on "most recent" as that will provide you with most up to date and relevant information pertaining to this product. I acquired my Fitbit Sense in June 2021, it has not yet been a month, but so far so good with 24/7 use. I am slow to check out and use all the features, but what I have interacted with so far has been stellar.
I have been using Fitbit products since April 2015- kinda have a love/hate relationship with this brand. I use the activity tracker constantly, and I greatly enjoy the app. So I have stuck with it as I upgraded over the years (Charge x2, Blaze x2, Versa 2, and now Sense). As with many Fitbit users, there is a known frustration with the products. Despite some of my own qualms, and having the ability to spend whatever I want on any fitness tracker I want, I still end up (so far) with this brand. Mostly because I haven't found a tracker and app that I totally like better. I even have a Garmin, but I find that so far off base of accuracy (save for HR), that it is a glorified watch. Garmin seems to do best for actual intended activities (going for a run, going for a long walk, going cycling) where it seems to not be accurate in steps for any other part of the day (only counts about 1/3 of actual steps unless engaged in a longer duration activity, and even then it takes a few minutes for it to start). Also, the app seems to have a lot of info, but doent really tell me anything. That being said, when it was time for me to buy another fitness tracker--I went from Versa 2 to Garmin.. back to Fitbit. I went with the Sense because the price was right, and it was an upgrade over the Versa 2. After my underwhelming experience with the Garmin, I would have happily taken over a 2nd hand Charge from 2015. At least my steps would be accurate.
Ok, so back to the Sense. WOW, the visual on the screen is really clear and precise. Even way more so over the Versa 2, and I had no issues with that. Set up was EASY, and QUICK. Basically, just like in adding any other fitbit, just let it pair and it will very quickly be all set and ready to go. I didnt have any weird upselling offerings, or at least nothing that wasn't fantastically easy to opt out from. Nothing shady that I saw.
ONE POINT that I DO think is important to know is that if you happen to have a Versa 2 (Not sure if this also happens with regular Versa, Versa Lite, or Versa 3), but this could not be added alongside my Versa 2. I had to take the Versa 2 offline in order to add this Sense. I know this is the case with trying to add more than one of the same products, yet I have always been able to have several Fitbits paired no problem, as long as they were different models. SO, I guess the Fitbit app sees Sense and Versa 2 as the same. Not a big deal as my Versa 2 had essentially died after I wore it on a hot humid day and my sweat killed it (then I brought it back to life after putting it in a bag of rice for about a week, Then afterward the battery was never the same. It drained to nothing daily.. and I needed to not have to worry about daily charging.. hence my picking up a Garmin in the interim to see if I liked them enough to spring for a more fancy model--nope-- and ended up buying the Sense.)
Hope it lasts. I love the look. The band is way better than the old pin style. Swapping out bands is so much quicker, easier, less need for super fine motor skills. LOVE the charger. It just sort of magnetizes to the fitbit. No need to clip in.
SP02 wasn't the main feature I was drawn to, but in order to have accurate use it seems a special clock face is needed, and that clock face will drain battery quicker (from what I have read). That being said,
Battery life has been excellent for me.
Love being able to add other apps, and features. Scrolling is easy, turning face on/off is not complicated.
HEART RATE is accurate. I have tested it against my garmin, two blood pressure devices, and a doctors appointment. All saying the same.
Also, I the voice assistant is great. You can choose GOOGLE Assistant, OR Alexa. This is why selecting most recent reviews on this sort of stuff is important, as the early release of Sense did not have Google Assistant, but would soon with an update. True, and they followed through as I have it.
AT THIS TIME, I have ZERO issues, concerns with this Fitbit Sense. I will be back to update as I learn more, or if I have anything worth sharing that is bad. I keep up with my reviews as needed.

Me gusto que la batería dura más de 5 días.
En relación a la calidad por el precio se me hace muy buena opción, desde mi punto de vista la mejor.
Una delle caratteristiche più significative del Fitbit Sense è il suo monitoraggio avanzato della salute del cuore. Grazie al suo sensore EDA, è in grado di misurare la tua risposta allo stress tramite l'analisi della conduttanza della pelle. Questo ti aiuta a individuare i momenti di stress e ad adottare strategie per gestirli in modo efficace, promuovendo un benessere mentale e fisico ottimale.
Inoltre, il Fitbit Sense è dotato di un ECG (elettrocardiogramma) integrato che ti consente di effettuare una valutazione rapida della tua salute cardiaca direttamente dal polso. Questa funzione è particolarmente utile per individuare eventuali irregolarità del battito cardiaco e consultare un medico in caso di necessità.
Oltre al monitoraggio del cuore, il Fitbit Sense offre una serie di altre funzionalità per il monitoraggio generale della salute, come il monitoraggio del sonno, del livello di ossigeno nel sangue, dell'attività fisica e del livello di stress. Questo ti consente di avere una visione completa del tuo benessere complessivo e di prendere decisioni informate per migliorare la tua salute.
Il design elegante e moderno del Fitbit Sense lo rende adatto a essere indossato in qualsiasi contesto, dal lavoro al fitness alla vita quotidiana. Il display AMOLED colorato e luminoso offre un'esperienza visiva nitida e chiara, consentendo di visualizzare facilmente tutte le tue statistiche di salute e notifiche importanti.
Tuttavia, il Fitbit Sense potrebbe risultare costoso rispetto ad altri smartwatch sul mercato. Tuttavia, considerando le sue numerose funzionalità per il monitoraggio della salute del cuore e il suo impegno verso il benessere degli utenti, molti potrebbero considerarlo un investimento valido nella propria salute a lungo termine.
In conclusione, il Fitbit Sense è un smartwatch evoluto che mette al centro la tua salute del cuore. Con una serie di funzionalità avanzate e strumenti di monitoraggio della salute, offre un supporto completo per il tuo benessere mentale e fisico, aiutandoti a vivere una vita più sana e felice.
