I've been a Fitbit user for a number of years, originally having the Flex 2 and most recently the Charge 3.
I found, as others had on the internet, that my Charge 3 was becoming increasingly frustrating and pretty useless when calculating my running and cycling distances. Growing ever frustrated, I switched to the Charge 4 on hearing Fitbit had introduced an in-built GPS, in the hope of having relatively accurate data.
On these grounds, I am not disappointed. The GPS is really very good, particularly for what you pay. Having tested in on a number of different runs and cycles, predominately in woodland, I've found that it's very accurate (particularly in comparison to the Charge 3).
I'm not so bothered about the Spotify or pay features (if you're UK-based), which I know others are grumbling about. In my opinion, if you want these sorts of features, you should look for a smartwatch. I find these sorts pretty gimmicky / useless if you're looking for a fitness tracker which isn't designed to be a smartwatch.
I've also not had the technical issues which some seem to have.
The battery is definitely nowhere near as good as the Charge 3. I suspect this is because of the GPS - which they DO advertise. I've noticed I'm having to plug in my Charge 4 twice at least twice as frequently as the Charge 3 (going for at least 3 runs and 2 cycles with GPS per week). This can be a little jarring if you're used to the battery of a Charge 3, but considering the size of the device with GPS running, I think people are being too harsh on the battery life.
All-in-all, I'm pleased with the device. Fundamentally, it's not going to let you run or cycle for 4+ hours using GPS (particularly in GPS challenging scenarios). If this is a problem for you, look elsewhere, but be aware you're not going to find a device which is as slim and powerful. I'd recommend this device if you're looking for a slimline activity tracker which is GPS enabled, it reads your heart-rate, has a sleep-tracker and connects to a clever app. The price and quality seem to be near-unrivalled in the field, so I really do think there have been some overly strong criticisms of this device.
