Stress Inducing Gadget
||Posted . Owned for less than 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Maybe too early to review given I’ve had it two days. But my first impression is terrible. I just came from a Pebble Time so that’s my comparison point. The watch has so far crashed on me 4 times. Go out of Bluetooth range for more than 30 minutes and the watch basically falls apart forgetting how to do anything. Like it forgot how to keep time. It lost 6 minutes after just two hours of being detached. I couldn’t access any features because it couldn’t remember how to repaint the screen and remove the previous screen. So everything just stacked on top of each other. It even refused to turn off the screen because I guess it forgot how to do that too. Find my phone and suddenly everything works as normal again. It is sluggish. It is confusing. Half the things you try on it it tells you to just open the app in your phone instead. I want it to show my emails but don’t vibrate every single time. Can’t do that. Going to wake you up on every spam. So no emails at all. And it only works with Gmail app or Outlook and nothing else. Want to hook up to Outlook for my calendar events at work. But no, if you do that it just notifies you about every single email and vibrates again. I get 1000 emails a day. So no events either. It emphasizes stress sensing. But this watch is so frustrating that it asks me every 40 minutes how I’m feeling because it detected something. I paid $300, you should be able to tell me. Why ask? Also my Pebble was set to vibrate if something bad happened so I’m conditioned to be stressed when my watch does this (on purpose). So no stress sensing either. At least battery life is surprisingly good and beats my 7+ year old Pebble with its 7+ year old battery. How Fitbit bought Pebble and Pebble failed is beyond me. The only good part is I’m a Total Tech member which means 60 day returns. I’m probably going to do so unless some major improvements come out by then. I’ll re-review if things get better.

Great smartwatch
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.My original Sense died so I upgraded to Sense 2. So far it's very similar. Functions well. Does all the things I want it to do. Battery is even better than expected. Loving it so far.

Great Health-Focused Smartwatch with Room to Grow
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I've been using the Fitbit Sense 2 for a few weeks now and I'm genuinely impressed. The health tracking features are top-notch—especially the stress management tools, heart rate monitoring, and sleep insights. The watch is super lightweight and comfortable, and the battery lasts me almost a full week, which is a huge plus. What I appreciate most is how it keeps me mindful of my daily wellness, not just steps or calories. That said, I do wish it supported more third-party apps or had music controls. Also, some features need Fitbit Premium, but I found the trial period useful to decide if it’s worth it. Overall, if you're looking for a fitness and wellness watch more than a smartwatch, this is a solid choice.

Fitbit Sense 2

New Fit
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Just bought this to replace my Versa 2, which I loved. I love the Sense2 with a few exceptions. With the Versa,, the Face was much easier to read. With this new one, so much information is placed on the “home” screen that it’s difficult to see the individual numbers. Otherwise it’s awesome.

4th Fitbit and great so far!
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is my 4th Fitbit over the years. I have had the Charge, Versa 2, Versa 3 and now the Sense 2. So far I like this watch, the features are good and the heart rate detection seems to be accurate for cardio (which was a big issue for me with the Versa 3). The app is super easy to use. Only negative (if you can even call it that) is that the band doesn't seem as pliable as the others but maybe I just need to break it in. All in all, good purchase.
