Fitbit Sense 2 Advanced Health and Fitness Smartwatch with Tools to Manage Stress and Sleep, ECG App, SpO2, 24/7 Heart Rate and GPS, Shadow Grey/Graphite, One Size (S & L Bands Included)

Best watch I’ve ever owned
The fit bit is the best fitness tool on the market. It is the only one that tracks cardio fitness that I know of. It is Comfortable weightless you can pick any size or color the battery life is superior to Apple. The display quality is great. The color on the screen is amazing.

All the features I could ask for and great battery life!
It does everything, and fairly well.The touch interface used to be almost useless. It was extremely jumpy and often detected a drag as a button press. They’ve massively improved it in the January 2025 update, but it still mis-detects drags as taps sometimes, and to very annoying outcomes. Like setting an alarm I didn’t want. Or registering my emotional state which I have to open the phone app to fix.But I’m perplexed why it doesn’t track routes climbed or elevation gains while climbing. Or why it doesn’t automatically detected climbing using geo-location. I climb at the same gym multiple times a week. It should know that I’m climbing when I go there and my heart rate elevates. Similarly, I think it should know when I’m at my weight-lifting gym. I’m tired of having to clumsily scroll through activities to pick the appropriate one. Heck, shouldn’t it know I’m swimming or surfing when I’m at the beach? Can’t it detect when it is submerged in water and activate the swim mode so that the touchscreen isn’t randomly detecting touches from water particles?The main reason I chose the Sense 2 over other options, was for the emotional state notifications. But they’re too delayed to help me recognize when I’m stressing and to relax. I frequently notice them hours after the event. I think the notification actually waits until I’m done stressing, rendering it useless for stress management. Frequently I get the notification ten minutes after the incident, but I think that might only be if it was a short-lived stressful event. My Garmin Vivo Active wristband was much better at this. It would vibrate and display a helpful meditative breathing exercise within a couple minutes of sensing my stress. It helped me massively improve my stress management. This watch on the other hand, is only good at recording stressful events. Or calming down when I recognize that I’m stressing out by myself. The EDA scan is really helpful in getting me to relax, but I have to know when to use it. I wish I didn’t have to tell it which type of stress I was experiencing every time; isn’t Google a machine learning company? Can’t it guess at what type of stress event I experienced?Some reviewers complained about delayed heart rate monitoring. I experienced that a couple times early on but they seem to have fixed the issue in an update.

Utterly worthless!
After 5 years of good service my old Versa was struggling to keep a charge for 24 hours so I decided to replace it with a Sense 2. Huge mistake!This device drops to 20% charge in about 12 hours and then requires charging for about 2 hours. You can wear it during the day or at night, but you really can’t do both unless you set aside a couple of hours for charging.The watch has all sorts of sensors, but they all need to be turned off if you want 12 hours of life. Searching the message boards this seems common. I will play with the recommendations Insee there for a couple more days before returning it, but I’m not hopefull.It is inexcusible for a company to try to market a product that falls so short of their written claims! Avoid Fitbit if you are looking for a smart watch!Update: Turning off things like stress management and a restart apear to have imroved the battery life. Yesterday it dropped to about 60% including a 40minute walk with the GPS on. Unfortunately, it won’t charge back to 100% in the time it takes me to shower and dress like my old Versa. So it is probably a charge twise a day affair rather than the advertized once every 6 days. As others have remarked, the HR monitor seems to be incredibly inaccurate. It takes quite a while to react when starting a vigourous exercise and the HR laghs the obvioud signs like heavy breathing by several minutes. It barely registers exercises like the rowing machine in spite of the evident level of exertion. On a very steep hill that left me huffing and puffing it barely cracked into the fat burn zone. For some reason, the weather app has decided to stop working, too. The Google Maps shows turns that have nothing to do with the route being shown on the phone. This came and went, but I certainly wouldn’t trust it if I needed to get somewhere. I’m still quite dissatisfied. More later…Well, I did get the weather app to work by turning location services to “always”. On days I don’t use GPS I can actually charge it during my morning shower and get close to 100%.The heart beat monitor continues to be awful. My old Versa was often slow to recognize exercise, but the Sense 2 can take 10 minutes to even notice increased heart rate.I started the trial offer on Premium but don’t see anything there that would persuade me to pay for it once the trial period ends.Further update – for some reason, the Sense 2 has begun to mistake driving for bicycling. Based on it’s claims, I should easily win the tour de france. Pretty good for an old fat guy😃Update after another month. The charging seems to have sorted itself out enough that I only need to charge once per day. The GPS IS some sort of random number generator, with the distance for the same exact walk varying by around 30% from day to day. Very brisk walks often show a slower pace than casual strolls.The Sense has begun to begrudgingly acknowledge my heart is beating during rowing sessions, but is wildly inaccurate. For the stationary bike it tends to not register anything, then overshoot to ridiculous levels before settling in to reasonable agreement with the HR monitor on the bike.The sleep logging seemed to stop at 14 days even though I have worn the Sense every night for at least 40 days. I’m not sure I care what my “sleep animal” is anyway – is this intended for children, or what???My next fitness tracker/smart watch will definitely not be Fitbit. I will miss having 7 or so years of history, but if most of it is bogus, who cares?

Nice step up from the Sense first version
A few more features than the first edition of the Sense. Really long battery life a large improvement. Easier to use than the first. I really like the user interface and a little more customizable which is very good. I am not happy that there will not be a Sense 3. Google wants you to buy their own watch which is very pricey for the features offered. I hope the Sense 2 lasts a long time.

Good product . Switched from Apple Watch 8 ( which crashed after 2 yrs of use) and find this so superior in terms of battery life. Features are almost same but this is a improved version for a better price

Ligero, dura la pila bastante, práctico y fácil de instalar!!!!
