Review: Back with Fitbit again! Updated review - So I got this delivered on lauch day (25th September) and have worn it every day and night since. I have had many fitbit trackers in the past and the last one was the Ionic. I gave up on the Ionic after a year because I had so many issues with it, the worst being it would loose connection with my phone for no reason and then I had to unpair, delete and re install time and time again. I have been using the Samsung galaxy watch active 2 since and it was an excellent smartwatch but its fitness tracking was not good mostly because of the calories burned during exercise which was so off. I was excited to see the Sense on the fitbit website before it launched and I decided to treat myself. I always buy from desertcart because their customer service and aftercare is excellent. Putting it simply I love this watch. It looks great, feels premium and the screen is bright and clear. I'm fully used to the haptic button and prefer it to an actual button as it means that the watch will be better protected from water. My only problem is that when doing strenuous exercise like spinning the heart rate sensor takes a while to register the high heart rate reached, sometimes my heart rate slows a bit before the watch catches up which meand I miss out on the top range readings of my heart rate. Also the watch seems to think my heart rate drops down into the 110 to 120 bpm after an intense interval but my heart rate is definitely still really high in between hard efforts so this does bother me. My Ionic did this when I first got it but it seemed to improve over time so I'm hoping that the Sense does too. My guess is that it is something software related which can be fixed. Also when weight training the watch puts my heart rate at 110 to 120 bpm when I know that after doing squats for 6 solid minutes with a weights bar my heart rate is way higher, my Samsung puts my heart rate at 140 to 150 bpm for this. Walking seems accurate as does martial arts and kick boxing. Maybe fitbit could fix this with an update. All of the features of this watch are great and I love it. I'm looking forward to seeing what updates come in the future to improve things. I'm especially looking forward to being able to answer phone calls on the watch as this was a big feature I enjoyed with my Samsung. The new os is nice and the connection to the phone is way more stable but it did drop out once so far and I had to unpair, delete and re install then it worked. I think that fitbit might be working on stability now as it needs to be better to be able to take calls on the watch so I'm guessing that's why we don't have that function yet. All in all I'm happy despite the niggles. I find this watch exciting. Update! My sense had to be sent back to fitbit today as it was faulty. I'm very happy with fitbit customer service so far as they are replacing my sense with very little effort to action this. Unfortunately though desertcart now don't replace faulty products after the 1st 30 days. They used to replace faulty products up to a year after purchase which is why I bought it from them. I will just buy from the manufacturer in the future now. I have to say the desertcart customer service lady was excellent, not her fault that the procedure has changed. Just thought this might be an important point to make incase anyone else buys from desertcart because of the returns policy which has now changed.
Review: Nice attractive watch - It is a very nice watch that has all the features you could ask for, heart rate monitoring, steps, sleep etc etc. I have mine linked to iPhone and whilst it works well with the Fitbit app itself, it doesn’t really play ball with Apple Health very well, so you have to decide which eco system you want to be in. If you are happy to do everything in the Fitbit app then that’s all you really need. The app records all your daily steps and workouts, either automatically or you can start them manually, and a built in GPS is nice for when you want to map your workout. At the moment I mainly just walk so I let it auto detect my walk and don’t have the GPS activated so it consumes less battery. After the walk it will pop up in your daily activities as a walk and will tell you how many steps you did on that walk, your heart rate and zones you were in such as fat burn or cardio so that is great. Sleep tracking seems to work well and seems to report how diabolical my sleep really is accurately. Build quality is very nice as well and it feels a premium product. I upgraded from a Fitbit Ionic to this Fitbit Sense and do feel it is a worthwhile upgrade, so no regrets there. It has plenty of customisation of styles to keep it interesting as well. I am basically using the Fitbit to try and lose some weight and get fitter again after a long period (since the pandemic started) of inactivity, so for me I find it a worthwhile tool to encourage you to make an effort to improve your health, and it has the application and hardware to achieve this if you are willing to work at it.

### ⭐⭐⭐⭐⭐ Back with Fitbit again! Updated review

### ⭐⭐⭐⭐ Good. But….
*by M***Y on 4 May 2022*

I bought this as an upgrade for a Charge 3 as I wanted to be able to access more health information, I did not buy it as a smart watch which to be honest is probably a good thing as it really isn’t one (yet?) I don’t use the voice features, call making feature, Spotify or most of the apps. Pros. I am impressed with the sleep tracking and all the other associated features which allow you to collect a large amount of health data. This of course relies on a Premium subscription. I have had no issues with the side button which some users have and the display can be viewed clearly even in bright sunlight of which the inability to do this was one of the major niggles of the Charge 3. This device also works with the Cardiogram app which was a question I was unable to find the answer to until after I’d bought it, it’s not listed as supported on the app details and I couldn’t find the answer online. Even though it’s a large watch it’s comfortable to wear night and day. Cons. Battery life, battery life, did I mention battery life. How Fitbit can claim six days is quite beyond me. Bear in mind I’m not using the ‘battery draining’ features and I needed to recharge on day 3. I turned off the GPS which has to be done on the watch itself not within the Fitbit app, no change. I ran the snore detector for a few nights and realised what I had always suspected, I don’t really snore so I turned that off too but I’m still charging on day 3. Most of the charge seems to go overnight so I guess it’s all the extra data collection during sleep that’s doing it. I have noticed that the charger is quite fussy about where it’s plugged in and charges faster when connected straight into a USB port and not into a mains adapter. I didn’t like the strap supplied so bought a cheap and cheerful fabric one which is really comfortable. I do worry about the robustness of the screen as it’s quite big and vulnerable to knocks and most screen protectors seem to prevent some of the features from working. To sum up. This device does what I bought it for which is to provide health data. I did not buy it as a smart watch and had I done so I would have been disappointed. It has lots of really useful features but the one factor which really lets It down is the poor battery life. Even with lots of features unused it is still half of that advertised by Fitbit. I think it’s important to be realistic in your expectations of this device as in reality it’s not where Fitbit would like it to be (or advertise it to be) in terms of its performance especially with regard to realistic battery life. I’ve given four stars as it meets my expectations but taken one off for the battery life issue. Update. July 22. As predicted a couple of small chips on the edge of the watch face caused by knocking it accidentally against things. The charger which came with the Fitbit stopped working earlier this week. The cheap unbranded alternative from Amazon seems to charge the device much faster than the original did…. Update. September 23. I have finally dropped Fitbit and purchased a Garmin watch. Reasons as follows, Battery life on Fitbit is dreadful and getting worse. Continued issues with the charger failing and no resolution from Fitbit. Fitbit have issued an update which has completely ruined the layout of the app and which cannot be changed. In addition since the update my Sense has failed to track my sleep. Fitbit has been taken over by Google and the Fitbit app will soon be removed and Fitbit will only be accessible via Google. My Garmin device gives me everything that Fitbit did with the exception of ECG monitoring (which I suspect wasn’t very accurate anyway) and flights of steps but without any premium subscription which saves me £80 a year. Sorry Fitbit but it’s goodbye from me.
