Fitbit FB512GLWT-FRCJK Advanced Smartwatch with Tools, Bluetooth - White

Review updated after more than a month of usage:Summary: If you have been oscillating between sense and apple watch 6 series, go for sense - battery life is what sealed the deal for me. Amazing beautiful watch - perfect companion for a journey to good health.Pros:1. Great battery life - I have been using this watch full blast with always on display and using the EDA sensor at least thrice a day, and installing and uninstalling so many watch faces. Third straight day, and the battery is still there.Edit: In a month I installed so many apps and watch faces and have now stabilised with select 5. Battery performance is superb. On weekends I forget to charge and it is cool.2. The EDA/ stress sensor: Very responsive. I checked the EDA scan feature a few times. It actually gave more EDA responses when I was a little stressed. Seems like a very handy tool for me - especially because I have had stress related issues in the past. It is a perfect companion for my daily meditation and Yoga practice too.Edit after a month usage: EDA/ stress sensor is good but it doesnt tell you anything you dont know already.For future edit: At times, I feel restless and anxious - and I calm myself by taking a quick walk around. Will check what the EDA scan says at that time. Will update - still havent faced the issue again.3. Heart rate tracker - It is fitbit's best. And fitbit is already the best out there in HR tracking. So no further comments.Edit after a month: At times while exercising, I feel there is a lag in the heartbeat numbers. Or maybe that's how our hearts work - they take some seconds before they can fire up. :) Will keep an eye on this.4. Notifications: Using with iPhone. Everything as expected. If it could show a preview of the image in messages, it would have been awesome! I did see this discussion happening in the fitbit developer forum - so I guess it is in the works.Edit after a month: Still no news on image in notifications. I don't mind this though.5. Step tracking - Precise.6. Sleep tracking - Sweet.Edit after a month: One of the most used features for me - everyday sleep score tracking is really helping me with my stress management. Recently got an 'excellent sleep' badge tag - for the first time in my 2 years of fitbit usage (wore Inspire HR earlier - that also tracked sleep)7. Band is too light - I have upgraded from fitbit inspire HR. Had used an after market stainless band for that - compared to that, the sense band is thin air. While sleeping, I tend to forget I am wearing the sense.8. Special tid-bits that I loved:a. It has a smart alarm feature - which wakes you up before your alarm if you complete a sleep cycle within half an hour of your upcoming alarm. This makes you wake up fresh af, instead of groggy - like the regular alarms do, if you are in the middle of your sleep cycle. Neat.b. Amazing watch-faces. A lot of free options to choose from. The one which allows personal photos to be put up as a watch face is cool. I bought a chronograph one for 1 dollar. Can change accent color as per my clothing. Pretty cool. Too many amazing watch faces.Edit after a month: Too many sweet free watch faces. Paying a dollar wasnt worth the purchase I made a month ago. :Dc. Many knick-knack apps you can install and try on. I like the weather app and the news app. Guess more will be coming soon. Flipboard doesnt work yet - guess it will work in future.Special trick: Made the ECG work in India by just changing the location to US in the app profile. No VPN required. Works like a charm! What an easy way to hoodwink the policy loopholes - guess it was designed that way - makes one an accomplice in cheating the policy, though. Smart...Cons:1. It is not apple smart watch. I know brand 'apple' is a deciding factor for many. This is not apple - but the build quality looks as good. Will have to see how this thing wears down over next few months/ years.2. Fitbit premium app : The free version of the app shows almost all the metrics (except a few detailed explanations, like the stress score details, monthly trends of sleep parameters etc.). While the sense comes with a 6 months membership of the premium part of the app, I would not really want to spend some 849 rs per month post 6 months of buying a 30k smartwatch! Fitbit guys - you need to curb your greed! Guess when google takes fitbit over, this issue will be sorted out.---Will update the review after a month of usage - DONE. Edited above.

Features, performance, app experience, premium subscription, active zone minutes, HRV and stress measurement.

Pros:Plethora of sensors.Well built and Good looks.Good display and is legible.Good charging mechanism.Excellent reports and reminders from Fitbit via mails.Cons:Not so easy and simple App. Confusing layout.No swipe feature to go back. Have to access the haptic feedback button which isn't easy or quick.Battery life without GPS is just 3 to 4 days which isn't great.Few features and in depth analysis is limited to premium membership which is a paid service.Synching and update issues at times.Most of the useful watchfaces are not free and need to be purchased which isn't fair.Loudspeaker volume too faint while using the smartwatch for calls.Overall a good concept that was quickly put into market wothout thorough implementation. Software updates also seems to be slow from fitbit.Everything seems to be working fine, but can't comment on the accuracy of the step counter, HR sensor etc.. as most of the these wearables are not of medical grade and should fall within the acceptable range to serve an appropriate indicative values.May be fitbit Sense 2 or 3 will be a well rounded product in future.Recommend this product with few sacrifices.

Worst experience1.) I have ordered black colour watch I don't know how it is changed to cream color while booking.2.) The main reason to order this Smartwatch with high budget is for music but there is no internal storage for music and there is an app called deezer which we can sync the music in watch but that deezer app is not working in india.3.) The SpO2 will working only while you sleep.4.) The fitbit app is not supporting in redmi4 mobile.5.) Not connecting to bluetooth earpods as well.6.) When a phone comes it is not showing in the watch.Please don't buy this...all my money is lost the dealer is not specifying the details of the product accurately.The customer service is even worst when I ask for an replacement for black color they said they cannot do it and dealer is also not responding properly..they even have the black color stock but not replacing with black color

Lovely smart watch, been using it for 2 months. Had to use ecg feature via hola proxy, now ecg app is available in india. The watch tracks it all and I think is the best in market..go for it

This watch is good in almost everything it promises!!It's sleep tracking is fantastic indeed!!Almost has everything a smart watch needs...But a bit pricey

I have been using Fitbit for a while.Good features - sleep, temperature, heart rate, activity.Needs work- stairs measurements.Urgent attention - even essential accessories like strap are unavailable in India. I have been looking for one for months, no luck. Ending up using an inferior quality duplicate.

The product is working extremely well since i purchased it!

I purchased this watch in April. It is now October 7 and it will not turn on. It will not reset. Yes, the battery is half full but just in case I left it on the charger for a couple hours. Still Nothing. It wasn't great for phone calls either. The volume is to low. I would not purchase another Fitbit. I'll give apple or samsung a go. This was a big waste of money.

長年blazeを使用。バッテリーの劣化も体感的にはなく、傷も殆どつかない頑丈さにそのまま使用していたが、新機種に興味が湧きApple Watchも範囲に入れ様々検討の上senseを購入。感覚的な違いは画面が少し綺麗になったかなという点とカスタマイズしやすい点。バッテリー持ちは公式の6日はさすがに無理でエクササイズや時計表示で触っていると持って4日程度。節約の為常時表示はオフにしているがGoogleアシスタントや天気の確認で使用するので頻繁に表示している。Apple Watchにしなかったのは圧倒的にこのバッテリー持ちがfitbitは良かった為。仕事上晩の充電が出来ない環境ではApple Watchの選択肢はなかった。iPhoneとの相性やデザイン性でApple Watchは捨て難かったがバッテリーが公式で18時間とありこれでは実用的でないと判断。しかし性能、コスパを考えればfitbitが正解かと。blazeに比べ操作性、レスポンスも向上しておりもっさり感もマシになっている。画面デザインはアプリから変更でき、多彩なデザインが用意されている。ベルトのフィット感も格段に向上しておりズレる事がなくフィットネスの時も邪魔に感じなくなった。反面密着度が高いのでかぶれ防止に汗をかいたら拭き取る必要がある程。ベルトサイズは長短2種類になり女性の腕にも問題なし。versa3と比較しストレス管理程度の差だったが価格が変わらないのでsenseを選択。ストレス管理は正直プレミアムに入らないと余り良くわからない気がしている。ちなみにSpotifyもプレミアム契約が必須。睡眠データに関してはblazeと変わらず。ただ、他のスマートウォッチと比べるとfitbitは詳細が分かりやすい。fitbitアプリを毎日開き同期して記録している。FiNCの体重計を保有しているのでFiNCアプリとも連動させ記録しているがバグなのか睡眠データは同期出来ない状況。歩数は同期出来ているので謎。ボディカラーは質実剛健なブラックと迷ったが今回はルナホワイトを選択。サイドのゴールド色が躊躇の理由だったが現物を見るとさほど派手なゴールド感はなく腕に馴染んだので良かった。腕を見る度テンションが少し上がるのが嬉しい。言い忘れたが血中酸素ウェルネスの表示がある。正確性は不明だが参考にはなるのではないか。基本的な事だが、これをつけると歩こう、良い睡眠を心掛けようというモチベーションアップに繋がる。それだけでも使う価値があると感じている。バッテリーの充電が面倒、という方にはfitbitがおすすめ。

Loved the watch - functionality and looks win. I love being able to use FitBit Pay and getting push messages, though the latter needed quite some settings adjustment on my phone, which is no fault of the watch's. Just one thing that is my biggest regret though - I started having allergic rashes that left itchy burn marks on my wrists and arms. So I used a transparent bandage to cover the charging contact points. Tracking functions aren't compromised, and I would only have to remove the tape for charging. Still loving the watch now, almost a month since I've switched from the smart watch with everlasting battery life - Amazfit Bip. Charging the FitBit Sense is almost an every other day affair. Considering the functionality, I can accept that.

This was given as a gift. She is very happy with the variety of options and the battery life. It is now mid April. Will not charge. Yikes.

PLEASE SEE EDIT AT THE END OF THIS REVIEWI've just upgraded to the Sense from the Versa 2. I loved my Versa 2; it did nearly everything I wanted it to do. However, the Sense measures ECG and that is what I wanted. Its taken a long time for that app to get approved by Health Canada. I was waiting for that, and for the watch to be in a sale as it's somewhat more expensive (nearly twice the price) of the Versa. This watch does quite a few things that the Versa 2 doesn't do. I feel that the screen of the Sense is slightly larger than the Versa 2 and the text on it seems larger and easier to read.It was pretty easy to set up because I already had the app on my phone. Pretty much as soon as I got the watch out of the box and switched it on, I was sitting next to my phone and it started setting itself up automatically without much help from me! I'm using a Samsung phone with it. I've been able to add apps to it with no problem at all.I would point out too, that if you use a CGM with your phone, (and if you use one you will know what that is) then you can also get notifications from the CGM to the watch. I use the Libre 2. The Versa 2 also was able to do that.The charger lead is different, and better than the charger lead that comes with the Versa. That charger lead was really awkward and in fact I found a better one on Amazon. The charger lead for the Sense attaches magnetically and is flat.Probably the only niggle is the strap. It fastens differently on the wrist than the other types of normal strap and I don't like it. I'll be looking for a different strap on Amazon.Apart from that small thing, I love the Sense as I thought I would. If you want a watch that allows you to have notifications from your phone for text, messenger, emails, phone calls, Alexa, alarms (I use mine to wake me up in the morning by vibrating on my wrist) and a whole host of other stuff, you'll like this. 😍EDITED TO INCLUDE AN UPDATE:I have just found out that I cannot upload my music to the Sense. It does not have that capacity. You can upload music if you buy a subscription to Deezer or Spotify. It seems very very odd that they should bring out an upgraded more expensive watch and then remove the ability to upload one's own music. There's a lot of unhappiness among Sense users who like me, did not bother to check on that small point because we assumed it would be the same. It seems that Fitbit has partnered with Deezer and Spotify and it's going to be earning them some dosh, so to hell with their customers, they don't care. So if this is a game changer for you, stick with your Versa 2.
