HOW did I live without this thing again?

Yes, I finally took the dive to Fitbit ownership. I must admit, I had considered it many times in the past, but because I lack the efficacy level to feel like I could possibly remember to wear things like this (let alone charge it,) I always procrastinated.

this fitbit is the best yet to hit the market, tracking all my progress right down to the slightest calorie intake and step taken to collect the mail. Having the ability to sync with my phone this fitbit doubles as a fitness product and a quick tool to reply to an important text while on the next big adventure or hike or jog!

This watch has helped me keep track of my daily activity and encouraged me to push further to meet my fitness goals. It feels great on the wrist being slim, the battery lasts about 5 days give or take, big display, and the health monitors are very accurate. The continuous EDA helps track my stress levels all day and follows up with questions on how I feel in the moment. AMOLED display looks great and is very responsive to the touch. The app can pull up your summaries for daily, weekly, or monthly for all areas that the watch tracks to give you a better picture of what your lifestyle is like. Overall I am very happy with Sense 2 with its great health monitoring, stress detection, and encouragement of more activity. The only thing I had trouble with at first was getting the time correct but with a couple of setting adjustments that issue was fixed quickly.

Very straightforward right out of the box which means a very easy diy set up. With user friendly instructions from setting it up to charging it really fast. Built to last and the bands are very easy on the skin. Leaves no rashs and your skin doesn't itch after wearing it for couple days. A very good smart watch that will keep you on a healthy track while keep those social media apps on your wrist. Easy to read messages and make phone calls! Very nice and fast charging watch!

Accurate Pedometer With Lots Of Useful Features!

I am a 38 year old Xennial that is definitely not technology addicted. I was a little hesitant about getting a smartwatch of this caliber since I really didn't "need" any tech beyond an accurate pedometer. I do have to say though that this FitBit Sense 2 Smartwatch has truly blown me away. As someone who can easily navigate life without being "connected", I am shocked that I feel that this smartwatch is a necessary assessory now. The battery life on this watch is great (it lasts about a week) and I find myself strategically timing the point in my day that I will put it on it's charger so that it won't miss any substantial data. I wear this thing 24/7. My favorite feature of this smartwatch is the connection it has with my Samsung Galaxy phone to deliver notifications to my wrist and it alerts me when my phone is ringing. I am a Stay At Home Mom that is busy (and that is an understatement), I am constantly running around and not with my phone in arms reach and it is so nice to not miss important texts or phone calls. I had a Ticwatch Smartwatch in the past that constantly dropped connection with my cell phone and I am happy to say that I haven't had any of those problems with the FitBit Sense 2. It has never dropped connection, not once. I do also have to say that the pedometer seems very accurate in comparison to many pedometers I've had in the past. We go to Disneyland often and I am always traversing the parks pushing a stroller and I've had many pedometers in the past not give me "credit" for pushing a stroller because my arms are not doing a swinging motion, not the case with the FitBit. I have definitely increased my activity since starting with my FitBit, I find myself marching in place in front of my bed at the end of the night to hit my 8,500 step goal. Another feature I use a lot is the Sleep Profile. I have Sleep Apnea and it is nice to compare data between my APAP machine and the FitBit. I can even see my blood oxygen saturation on the FitBit and compare it to my apnea data on my APAP machine. I can see on my FitBit how much better my apneas are getting now that I am losing weight. Another great difference I noticed with the FitBit in comparison to other smartwatches I've used is that when you take off the watch the O2 sensor (red blinking light) eventually turns off so it's not wasting battery. The only negative about the FitBit Sense 2 is the silicone band that it comes with. Like many others, it irritates my skin into a yeast infection and rash if there is any moisture on my wrist, and it's a fitness watch so the goal is to sweat. I wish that the basic band that came with the watch would be made of nylon or fabric. Otherwise, this FitBit Sense 2 Smartwatch is great! I highly recommend it!

The fitbit sense 2 is a absolutely beautiful watch. Extremely high quality and well made, and battery lasts nearly all week. You really can't want anymore in a smart watch. It also integrates with Alexa which is an added bonus. Definitely recommend the fitbit sense 2.

At first I hated this Fitbit. Was nothing like the one I had before. After some tweaking I'm learning to like it. The screen I chose was apparently draining my battery somehow, didn't realize that could happen but once I changed it my battery life went through the roof. I miss the raise to wake feature my other one had. I have to push the side button to light up the screen and pushing it again doesn't turn it off, takes me to the app window. No biggie, just takes some getting used to. The screen I chose has the date, time, battery, heart rate, steps and calories burned. I can read texts easily and see who is calling. I'm having trouble keeping it connectedness to the wifi though. Still troubleshooting that. It also has an exercise tracker but I keep forgetting to turn it in when I get on the treadmill. Overall I'm really liking this Fitbit. At first I almost hated it but it's definitely growing in me.

At first, I thought this was a really great product. It looks good, the battery life is good, and it has many health-related features. However, there are also some dealbreakers. It doesn't seem to work with Google Assistant or Maps. It lacks music playback control. I've also had some trouble with it disconnecting from wifi. It's a cool health-focused watch, but I don't think it's a smart watch.

Yes, I finally took the dive to Fitbit ownership. I must admit, I had considered it many times in the past, but because I lack the efficacy level to feel like I could possibly remember to wear things like this (let alone charge it,) I always procrastinated. But, I did it, the pristine, sleep and heavily touted Sense 2 was now fully charged and on the wrist, ready to win the day. Maybe? Out of the box, its pretty, very modern while also going with pretty much ANYthing you could wear (Yep, I wore it to a formal event.) This thing really does do a ton of things, many of which I didn't realize it was capable of: IMPRESSIVELY Fast charging (great because I'm terrible about this, like I said,) not only does it monitor exercise but also gives you reminders when you've sat too long (I ADORE this part,) it links with a scale, has alarms you can set, notifications from your phone, Do Not Disburb modes, senses sleep (so it doesnt disturb you,) AND not only does it analyze your sleep, it shows you exactly your variance of oxygenation which is super helpful if you're like my husband and have apnea issues... or think you might. It also of course does the stuff most know about including heart rate monitoring, cardiac episode monitoring (which in itself can save your life and is well worth the price of the watch,) amount of REM sleep and all sleep cycles, Calories burned in an exercise and a full day, Extensive weather forecasts, and a lot of stuff I'm sure I'm not mentioning... Oh! AND it's a pretty nice looking digital watch ;) One of my favorite ideas about this , is that is keeps collecting data and as it does, it gives you a much more accurate picture of your body's general performance/health. Much like how a Metastudy is a much more detailed and accurate picture than just a study, the more you wear this, the better, clearer picture of yourself you'll get... and WITH this info, it gives you tips on how to tweak your behaviors in order to be generally BETTER, and who doesn't want this?! Did I forget to wear this a lot? Yep, the first two weeks were frustrating on that front. In fact, once I even did a reversal in the driveway on my way to work to run back to get it. But like anything, its not hard to get used to, and I'm always forgetting I have it on. As I said before the charging ability of this thing is absurdly fast, which is great because most of the time, I'm forget to plug it in for a few days and just charge it on a car ride and it'd be full by the time I was at work. This is a little machine of straight up data you can use to immediately change behaviors and improve your life. I don't know about you, but I've spent a ton more on things that hardly did anything on that front. Nice to know there's a product out there that doesn't claim its a miracle, and still manages to change peoples lives much more than any miracle-cures I've seen!! < Just a sec guys, forgot to grab my Fitbit, I'll brb> :)
