Google Fitbit Sense 2 Health and Fitness Smartwatch with built-in GPS, advanced health features, up to 6 days battery life - Compatible with iOS 15 or higher & Android OS 9.0 or higher

I cannot understand how so much technology is packed into such a tiny device.The Sense 2 is astonishing. The number of sensors it contains is simply amazing. I've been on a diet for the past few months and use the fitbit daily, not just to monitor steps, but to see how my general health improves. This includes sleep quality, readiness, resting heart rate, breathing rate, heart rate variability, blood oxygen levels, ECG, and more. The data it produces is simply incredible. Personally I think it's really good valuable money, and as essential part of my daily routine. It's very easy to use, and definitely has far fewer Bluetooth sync issues than Fitbits I've owned in the past.I find myself charging the Sense 2 every 4 to 5 days. The battery life is incredible considering some sensors are running 24/7.I had to return the first Sense 2 that I bought as the touch screen was very unresponsive. However amazon were very quick in sending out a replacement and I have had no issues with this one.

Wish I had got it sooner as it tracks everything, it has made me lose weight, get better cardio, better sleep and it motivates me. I only had the basic fitbit before that lasted 8 year! I read up on so many before I decided to buy this one and it’s best purchase I’ve made.

All the bells and whistles of a modern smart watch. It seems show your heart rate a bit higher than it actually is. I checked online and I'm notbthe inly one who noticed.Getting NFC payments on it for that price is a pretty good deal though.

Really impressed with Fitbit,does Everything I need

Couldn’t be without itHad one for 6 years love it

This is the third Fitbit I've owned. And it's going to be the last.My previous Fitbit (a Blaze) was, according to my Amazon order history, bought in 2016. It lasted until 2023 before it failed, with what I think was a charging issue. That's seven years, which is a decent lifespan for tech. I replaced it with one of these, a Sense 2.It's always been problematic. The touch screen and settings are unnecessarily fiddly compared to the Blaze, and, although it has additional feautres, it's also missing a couple that I was used to. But, it was tolerable.Until last week. A firmware update (which is permanent, I can't roll it back) has effectively rendered it unusable. In theory, it still works, and it's still recording steps. But... it's taken on a life of its own. What it's doing is sensing phantom touches on the screen, even when there's nothing touching it at all. So it will randomly switch into a different mode, start logging an exercise, or change the settings.It's not just being over-sensitive to actual touch (eg, picking up my sleeve as it brushes the screen). I can take it off my wrist, put it down on the desk in front of me, and watch it behave as if I'm scrolling through apps and settings and tapping on them.Rebooting it fixes the issue, at least for an hour or so (usually), which is another indication that it's the firmware at fault rather than actual touch on the screen. But, sooner or later, it starts misbehaving again.I might, just might, have taken that as a cue to try a different Fitbit device, had Google not also recently taken the decision to downgrade the customer account UI, in the process removing features that I was using every day. A device which isn't working reliably coupled to an account that's been downgraded in functionality means that my next smartwatch is going to be a different brand.

Quick Summary - The features you are getting with this watch are NOT worth the price point. You can’t even control your music or download 3rd party apps. The health tracking features are available on other watches for less. Also Fitbit premium means that its arguably best selling point of in depth health stats becomes locked behind a monthly paywall after the trial. If you want an exclusive fitness tracker and don’t care much about ‘smart’ features (eg Google Maps), if you really want a Fitbit (getting worse because of their google ownership trying to sell Pixel watches instead) get the Charge 5 (£100 and pretty much the same features for half the price), or a Garmin (better at tracking exercises/health metrics). If you care about smart features as well as health tracking, (for Android) get a Pixel Watch (2nd hand around £150)/Galaxy Watch 4/5 or (for Apple) get the Apple Watch SE (2nd Gen) for slightly more money. It is a shame but there’s no really argument or selling point for this watch, as the price does it no favours. You can either get pretty much the same for less money, or spend slightly more and get a whole lot more. Apart from being comfy to wear and looking good on my wrist, it was just an overpriced tracker. (I returned it)In Depth Review-I really did want to like this watch. From what I’ve seen Google really stripped it to the absolute barebones that it can be, to the point where there’s no real reason to this watch over a Charge 5 for half the price, for example.The Heart rate tracker seemingly worked fine, I don’t have anything to compare it with but readings didn’t seem too unrealistic/inconsistent enough to be considered inaccurate. GPS was definitely hit or miss, 1 run the watch had recorded the route going all over the place, whereas the next recorded run (doing the same route) was perfectly tracked. The sleep tracker was interesting, something I checked each morning for the few days that I had the watch on, but I could see that feature over time be checked less and less. As for the other features, I pretty much forgot that they existed, as personally those stats didn’t interest me as much as I thought they would. Also take into account, if you’re still using this watch after the 6 month trial, the in-depth readings will be locked away from you unless you pay monthly for the premium subscription.The battery life was very good. I wore it for 6 days, with a recorded run, walk or weightlifting session pretty much every day. It ended up with about 20% left when I took it off to return it.There are no 3rd party apps, Google Maps being the only non Fitbit one. Maps worked ok, but was pretty unclear at times. It would for some reason remove how far you have until the next direction, so you could either be walking in a straight line for 20 minutes or 2 minutes and have no way of telling which, without looking at your phone (kind of eliminates the point of the watch). Also, in my experience, it didn’t let me know that I had arrived so I ended up walking past my destination a couple of times. You don’t actually see a map like on other smartwatches too. I think it is too unreliable for me to properly trust for regular usage.Watch faces are ok, there are a lot of them but some need to be purchased. On the main watch face, the weather would often be just displayed as “—°” even after syncing to my phone numerous times. Occasionally notifications would stop coming through. You can either have the display as ‘always on’ or activated by a button, which was sometimes inconvenient if I wanted to just check the time whilst something was in my other hand.The watch was comfy to wear and would be easy to forget about once on your wrist. It didn’t irritate my skin at all.Overall, it is a good watch and I was going to keep it, but after talking about watches with a friend I ended up looking more on Amazon and just finding out how lacklustre it is for the price. I returned it to get an Apple Watch, which will have all the fitness features I used on this watch and more because of 3rd party app support. If that does not interest you, save your money and get a Charge or a Garmin.
