Quality Smart Watch

Reviewed in the United States on April 29, 2024

I highly recommend this smart watch for anyone who wants to track their health and fitness. This watch comes with many features and is easy to use. My daughter is able to get her Dexcom notifications as well. I enjoy being able to monitor my heart rate, steps, sleep, activity levels, and many other health features. I can also receive text messages and other notifications. It is easy to use, set up and maintain. The app itself also is easy to navigate. I like the large square face to the watch, helps being able to see things clearly and you can customize it as well. Battery life is very good, the more apps running and customized wall paper i noticed a slight battery extra draw but nothing that causes the function of the watch to become unreliable or in constant charging. Very happy with the purchase.

Easy to customize the app and watch to my needs

Reviewed in the United States on June 14, 2023

I purchased this watch primarily for its continuous heart monitoring, ECG app, sleep monitoring, plus some basic fitness like steps and stairs.

It was easy to install. I was pleased to be able to turn off the GPS and Alexa which may have been good for an extra day of battery life. I was able to turn off the fitness nags. I've been running and working out over 40 years and don't need nags. I was also able to skip the Premium service since I don't want a monthly bill and don't want other nagging.

There are a huge number of watch faces available. I focused only on free watch faces. One thing that wasn't clear is that apparently you can only install 6 faces on the watch. When I found a better choice, it wouldn't install and had no useful explanation of why not. I ended up looking specifically for watch faces that included a battery indicator (surprisingly not universal!) and basic fitness figures. The hard part was finding watch faces that increased the font size of the battery % and fitness figures so they were more easily legible to older eyes.

The biggest problem is with the watch band. I have a narrow wrist and bands with holes like the OEM band are never spaced in a way that fits well. So I ordered a new band that is metal mesh and uses a clamp to fix the length. That works to get a comfortable fit, but is a pain to put on. Good thing I only take the watch off once a day! So I tried another watch band that had a folding clasp, like my old watch band, and is adjusted in length by removing links. The whole process of removing links was a serious pain, requiring a magnifying ring light and great patience. And the link removal did not yield a snug and comfortable fit, just as with the OEM watch band. Back to the band that works, for now.

Update. I just discovered it is possible, apparently, to get an adapter from my old watch band that attaches to the watch with pins to the FitBit clamp system. I'm hoping that will allow me to use my old watch band which was excellent.

This adapter took a long time to arrive all the way from China, but it worked perfectly. My old watch band was a 20mm band with adjustable sizing clamp and a folding clasp to take it on and off:

Now I have the best of all worlds. A good watch and it is easy to put on and take off with a snug fit. I wonder why no one seems to make this style of watch band specifically to fit the FitBit?

I like it but does not always work properly.

Reviewed in the United States on April 26, 2024

The watch is beautiful and has a lot of features, but the features does not always work properly. At 30% it is telling you to charge the battery. The on-wrist calls works sometimes, and sometimes it doesn't.

Dependable

Updated my first Sense to this model. I like the improvements and even the ease of setup. There were a few hitches in the setup but were easily figured out via YouTube videos. Fitbit itself is now Google and their customer service is no longer the best. The community feature does help with other owners posting recommendations when you run into a problem that isn't a problem but a learning issue. I'd switched to Samsung Galaxy for a while, but the Sense/Fitbit--in particular this model is superior. It is much more accurate, and their app is easy to load and follow.

Utterly worthless!

Reviewed in the United States on June 23, 2023

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?
