    After doing extreme due diligence, I pulled the trigger during the cyber Monday sale. It includes 6mo Fitbit premium subscription at no additional charge – important feature to save your learned trends and offer insights and statistics you don’t normally have in the Fitbit app without the premium subscription. AMAZING 7 day battery life for a change! Every feature works accurately as designed and specified as I tested the live EKG while at my cardiologist’s office and the results were identical. I’ve been tracking my sleep since my first Fitbit Charge 2 and as old as that was, it was also as accurate. As someone with A-Fib, it saves sessions of arrhythmia in PDF form so I can quickly and easily send it to my cardiologist. During sleep, it measures your heart rate variability, your specific oxygen levels SPO2, your breathing rate in how many breaths per minute and does every single activity monitoring application that all other activity watches do. This is by far the best value for the market. Especially considering that if you were to try and do all day heart rate monitoring and sleep monitoring with an iWatch, it would be dead already while you were halfway asleep. On board it has Google wallet, Google maps and other applications you can add such as find my phone, other watch faces, etc. If you are looking for literally the best watch for the money, features, battery life etc, the Sense 2 is for you! I’m not a bot nor am I paid for this review; just an actual real review by a pleased customer.

    Purchased Fitbit Sense 2Fitbit is the only fitness watch I’ve been happy with.Last week I thought I’d go with a galaxy watch 5 pro when I lost my last Fitbit Sense on a roller coaster. I was lured by all of the cool extras they offered. Galaxy did not offer a desktop dashboard though. It was a dealbreaker. Samsung Galaxy Watches blow. I mean who is going to look at days, weeks, months and years of progress towards goals on a watch? It was ridiculous. I never thought to see if they had a desktop dashboard because well, it was a no brainer that they would. I immediately, upon discovery, packed it up and returned it no matter the extras that they offered. May suit others but it did not suit my needs.I had a Fitbit Sense for a long time. Lost it. Replaced it Galaxy Watch5 Pro. Returned that. Replaced it with Fitbit Sense 2. This is the only fitness watch I will use and, the only fitness watch I will recommend.I read a lot of reviews of people whining about the changes from the original Sense to the Sense 2. If you never had an original Fitbit Sense, you are going to love it most likely.If you have used an original Fitbit Sense, in my opinion, there is nothing that should make you whine over the changes. So there is a more easily accessible button, bonus, so you have to relearn which way to swipe to find your information. Not a big deal. We are creatures of habit and don’t like change. But, I can learn new things. Why can’t you?Fitbit provides a bounty of useful information, a massive accumulation of personal statistics. I use a lot of the features at the gym or during physical activities. I use the step counter to make sure I hit as close to 18k per day as I can. I pour over the sleep information and am improving my sleep because of it. I have not confirmed accuracy of things like temperature etc etc but that doesn’t matter because whether it is 99 percent accurate or 96 percent accurate, I am looking at trends, up, down or neutral. As long as it is consistently accurate or inaccurate, in other words if it is inaccurate, as long as it is inconsistently innacurate is what matters. I look for trends. I do not pay any attention to the “feelings/stress” features but maybe one day I will. I don’t need music streaming. All reviews for every watch that offers it state there are problems with that feature. I use many other features. The fitbit dashboard offers a wealth of information not offered on the face of the watch because well, that would be ridiculous (Galaxy!). Please be ware, in order to utilize the complete package and all of the goodies Fitbit offers you will need to subscribe for 9.99 / month. You are not required but you might want to. For me, it is well worth it.Fitbit does everything right. The offer a sound, durable, sick-sleek watch, chock full of utilities and assessments and useful information. And, if it’s not useful, who wants it? If I don’t need it, I don’t want it.This watch is enough for me and I don’t even use all of the features.Go Fitbit! I heard you were sliding down a slippery slope with competition. You’ve got my support!

    I liked everything about it outside of it not picking up my calories burned while I’m at the gym on the elliptical unless I’m doing something wrong. It stays charge for a good while love that.

    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.Further update:https://www.amazon.com/dp/B0BN1RVM5W?psc=1&ref=ppx_yo2ov_dt_b_product_detailsThis 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:https://www.amazon.com/gp/product/B08CY5D2LB/ref=pe_2313400_740551120_em_1p_0_lm?th=1Now 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?

    The features on the Sense 2 work well and the watch offers a selection of crisp and easy to congured options. The health related features were the discriminator for my selection of this smart watch. The results are reliable and accurate, the price is a bargain compared to other smartwatches. Very happy with the Sense 2 and would recommend it.

    I had the charge 5 before I upgraded to the sense 2 about 4 months ago and I am very happy with the decision to upgrade. It’s awesome in every way. I couple things I don’t is that you have to tap a few times to get the screen to light up or just use the actual button on the side. Not a super big deal but the charge 5 was more sensitive and always lit up when you tapped. So that’s a little annoying but not a deal breaker. There is also a stat menu that I really love as it has all your numbers in one spot but if you try to swipe while in that menu you can accidentally remove a stat because you hide that stat instead of swiping to the next screen. Again no big deal but slightly annoying.I love everything about this fitbit. This one also has yoga as an exercise… not that I track it for exercise but it’s nice to be able to track the times I am remembering to take a break. I would buy this again and I am happy with my upgrade.

    I updated from a Fitbit Charge 4 to the Sense 2. I wasn’t sure I needed all the upgrades and the full screen after the simplicity of the Charge 4, but I have to say I was pleasantly surprised by how much I am enjoying the Sense 2 experience. The screen makes it easy to access and read all my vitals. The added functionality allows for better fitness tracking. I love how it establishes your normal readings and alerts to is anything us outside normal. I am happy with my upgrade. As an added bonus, there is a huge variety of color and style in replacement bands if you enjoy making your tracker part of your fashion, including some nice leather and stainless steel option.

    I have been a fitbit customer since 2015. I bought my sense 2 in the summer 2023. I love the extra battery length, etc. I had an issue with my watch in December. I contacted them and they replaced my watch. Great customer service.
