Fitbit Sense 2
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.My 3rd one! I love the sleeping app. Never did the membership. If you buy the watch you shouldn’t have to pay for membership (3 Stars due to membership fee). Not sure about battery life yet.

||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It’s not as big as I thought it would be. I had a small Fitbit before. I was interested in the stress feature.
I would recommend this to a friendNot even close to a garmin
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Performance, accuracy, battery life, features are all substandard to a garmin. With the new google app the fitbit interface looks neglected.

Great….for a while.
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this product just 1 year and one month ago today. It eas great at first, i was tracking and recording my heart rate during the day, sleep at night, etc. unfortunately, it has begun to fall apart. I attempted to contact the company but no one is available. This product costed me $300 and last just a year… retail prices with “Temu” quality.

||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It's been a great help in tracking everything. I especially like that it connects to my text & email. I love it.
I would recommend this to a friendDon't buy open box!!!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.In about 15 days it no longer worked and after having to go to the store because the app would not allow me to do the replacement option I get there to find out because it was an open box deal in "excellent" condition The only thing I can do is replace it with another open box but instead was offered one in fair condition. Even with total member rewards I was told they can only send it out if they're able to fix it great, if not then the only other option is to be refunded but they will not replace it with a new one.....

I would recommend this to a friendGreat watch
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love the features and so customizable. I added a metal band.
I would recommend this to a friendWatch only lasted a year and a half.
||Posted . Owned for 1.5 years when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This was a good watch until the little metal strip on the back fell off. The watch is worthless without it. It’s obvious a manufacturer defect because 3 weeks after mine feel off so did my husbands. They were roughly the same age. This watch was way too expensive for it to fall apart like it did. The rubber that the metal strip is attached to is disintegrating.

||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Only have had this for a year and a few months and it’s already falling apart. Battery doesn’t last as stated. I would definitely say it’s not worth what I paid for.

Game-Changer for Health & Wellness
||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 (Graphite, 2022) for several months now, and it’s hands-down the best smartwatch I’ve owned. The sleek design looks great on my wrist, whether I’m at the gym or in a meeting, and it’s incredibly lightweight and comfortable for all-day wear. The health features are where this thing really shines. I love the continuous heart rate monitoring, stress management tools, and EDA sensor. The built-in ECG and SpO2 tracking give me peace of mind, especially when it comes to heart health. Sleep tracking is detailed and surprisingly accurate — it’s helped me identify patterns and improve my sleep quality. Battery life is solid — I easily get 6+ days on a single charge, which is so convenient. The interface is smooth, the touchscreen is responsive, and it syncs effortlessly with my phone. I also appreciate the built-in GPS and guided breathing sessions. If you’re serious about your health, fitness, or just want a smarter way to stay connected without being glued to your phone, the Fitbit Sense 2 is worth every penny. Highly recommend!
