Review: Best price/performer on the market - This watch is fantastically functional: it does everything a watch should do and costs far less than the Apple watches. The best part is that it goes days without needing to be charged, and charges completely in about 30 minutes. I keep a charging cable in my car and just pop it on while I’m driving. The charging cables are a little funky, but replacements online are inexpensive so when the pins on one die, I just replace it. The only thing I don’t like is the wrist band that comes with it. Fortunately there are many third party options available so you can choose what you like. I have mine paired with my iPhone and it does a good job of tracking everything. It even starts tracking for walking and biking automatically when I forget to tell it and recognizes when I’ve stopped. Sleep tracking is also useful - just don’t get the idea that it’s perfect and you should do everything it tells you. Sometimes the “readiness” rating seems suspect. Still trying to decide whether I like the new AI “Coach”. It gives useful device that matches advice from my trainer, but it’s a little too chatty for my taste and sometimes goes off trying to solve a problem that doesn’t really exist.
Review: Beautiful Tracker, Great Features, No Problems Using in the Pool - Update to my previous review: Leaving at 5 stars for quality, durability, and features. Battery life seems to be about the same as my old Fitbit HR. Initially, I got about 5 days out of the first couple of charges. Now I'm getting about 3-4. I have no problem with that. I charge my phone more often so I don't know why I would expect more from my fitness device. How quickly the battery drains seems to be dependent on my level of activity. I just check every day to see how much it's drained so I don't get caught out with a dead battery. Haven't allowed it to go less than 20%. It does not track steps accurately when I do pool exercises. I manually calculated about 2400 steps during my pool therapy and the tracker only counted a bit over 1900, including steps walking to and from the pool and so forth. All total, there should have been closer to 3000 steps so that's a pretty big disparity. Frankly, I have not found any fitness tracker to be very accurate with step count during exercise as it depends on how much arm swing is involved. Previous Review: Received my Fitbit Sense 2 (Mist blue and light gold) a few days ago and I love almost everything about this fitness tracker. The mist blue color is a pale blue-grey. The watch casing is a soft gold color like you might see on a car. It matches the seller's photo perfectly (on my PC monitor anyway.) I think it's very pretty, albeit larger than I like in a watch. I have tiny wrists and large watch bands/faces are awkward on me. But, to get the features I wanted, it's worth getting used to. I don't care for silicone bands as they don't breathe but I suppose for a sport watch, it might be the best option. The buckling system was concerning for me because you have to pop the band hole over a pin, then tuck it under on the other side against your wrist. It looked like it would be uncomfortable to clasp it and wear, but I'm happy to say it's not. Just feels a bit weird to me because it's bulky for my wrist size. It was relatively easy to set up. The only difficulty I had was when I logged into my Fitbit app previously associated with my Fitbit Charge HR, it kept asking me to log into my account, but I was already logged in. When I entered my password, it said it was incorrect but it wasn't. I finally tried using my email PW and got into my account. What was confusing was, the Fitbit logo was at the top next to, "log into your account." So, buyer be aware, if you have to log into an existing Fitbit account, they want your email address/PW, not Fitbit PW. The biggest reason I chose this model was for water use. I have to do pool therapy and wanted all my steps and activities to be logged in real-time. I wore it in the pool, hot tub, and shower today and there were no problems with it at all. Just be sure to read all the instructions carefully. You can get more info on the Fitbit website for details on setup, use, and care. The device only came with quick setup instructions in the box. I haven't really paid much attention to the sleep tracking as I have a sleep number bed that tracks that. And I haven't compared it against another heart rate monitor. However, based on the level of activity and how I felt during pool walking and exercises, it seemed like the numbers were relatively accurate. My favorite feature is the hourly buzz to get moving. It not only buzzes on my wrist to alert me it's time to move, but after I get up and walk around, it buzzes again to let me know I've completed 250 steps (based on my current setup.) This feature is priceless as I sit at a PC all day and forget to move. Overall, 3 days in, I'm very happy with this purchase and feel that the price was fair compared to similar devices with the same features. It also came with 6 months of free premium app services which I appreciate because it gives me a good amount of time to decide if I want to continue with the premium for a monthly fee. I do not find that app either intuitive or user-friendly and it will take some time for me to get the hang of using it. Should I run into any problems with my Sense 2 in the future I'll update this review.

## Questions & Answers

**Q: heart rate including afib will report to an Iphone 12?**
A: FitBit Sense 2 works with iPhone that has an operating system of OS 14.  I have an iPhone 7 with an OS 15 and it works just fine.  Hope this helps.

**Q: Why did the price change back to full price yesterday from $79.95 when I attempted to purchase two of these items?**
A: It was a "DOORBUSTER" for black Friday/cyber Monday
 The price was SIGNIFICANTLY below even wholesale price. 

Prices of retail products fluctuate EVERY DAY, even SEVERAL TIMES A DAY. This could either be the retailer OR it could be Amazon OR could be the product company.

In the case of the super sale on the FitBit Sense 2, the sale was ONE PER CUSTOMER and ONE PER ADDRESS.
I know, I tried to do the same. (I did get one).
The idea was cooperative with Amazon the retailer as part of the black Friday/cyber Monday sale AND Google (FitBit) helped absorb most of the price. They were trying to increase their customer base and the Sense2 was a promotion in order to try to hook users on to a subscription model of profit raising.
They just don't want a 200 dollar sale, they want to get you to pay 80-120 a year. Like ALL products, whether it be a piece of software, or a peloton, there are upfront costs AND back end costs.

Even though you and I were trying to buy gifts, there were other people doing what is called "retail arbitrage"> There were independent retailers that thought they could buy a 65 inch TV, a 50 inch TV, a Fitbit, all below wholesale price, and then re-sell it

**Q: Is it water resistant?**
A: Depends on what kind of water resistance. I shower with it and no problems but the screen keeps waking up and it seems like water triggers it to push some buttons on the screen... I think this can survive a swimming pool too

**Q: Which features are premium only?**
A: Daily readiness score, a breakdown of stress management score, health metrics trends for past 90 days, wellness report, advanced skin temp. Details, over 200 workouts and mindfulness sessions, a breakdown of sleep score and, blood glucose trend which you need a comparable glucose meter and Bluetooth .

### ⭐⭐⭐⭐⭐ Has actually changed my life
*by F***S on June 4, 2026*

I've always been into fitness and health. I've always wanted to track my steps but didn't want some dumb looking smart watch on me all the time. BUT. This watch looks expensive and nice like an apple watch. Not to say thats what you're buying it for but it absolutely doesn't look stupid. It's almost like a game every day to see how many steps you can get. I am 6'1 and went from 243 pounds to about 223 pounds in just 3 months. It's insane. I already had the ability to be in okayish shape but this has changed my life for the better. For 220 dollars this might be the best investment anyone can ever make. Also tracks sleep so you dont have to pay a small fortune for a whoop ring
