Ranked in these QuestionsQuestion Ranking
Pros
Pro Continuous heart rate tracking eliminates risk of forgetting to activate the feature
The Fitbit Surge fitness tracker has automatic, continuous, wrist based heart rate tracking. Heart rate data is stored at one second intervals during exercise, and at five second intervals during non-exercise activities.
Pro LCD screen that can display multiple stats without the need of using the app
Similar fitness trackers depend on Bluetooth in order to relay info to a smartphone. Fitbit Surge can display information locally on the display which is far more convenient.

Pro Lets users log meals by voice
Users can tell Surge what was eaten, and a database will be used to match the entry with nutritional information.
Pro Does not need to be recharged frequently
The battery lasts 5-7 days which is one of the longer lasting options for rechargeable fitness trackers.

Pro Easy to operate compared to display-less options
While Surge easily syncs with iOS, Android, and Windows phones, it does not depend on them for functionality. The touch screen and physical buttons are a huge step up from display-less models.
Pro Informative and clear display that's easy to read
For its size, the Alta fitness tracker has a large display. The display will show steps, distance, calories burned, active minutes, and sleep time. You can switch between these by tapping the side of the display (there is no button). The screen is easy to read at a glance while on the move except in bright settings.
Pro Many different wrist band options available to suit your taste
The Alta itself comes in 4 colors: black, teal, purple and plum.
While expensive, you can swap out the band. Classic bands cost $30, leather bands cost $60, and stainless steel bands cost $100.
Pro Reminds you to move every hour
The Alta will remind you about your move alerts each hour. By default, it suggests 250 steps each hour and it will vibrate 10 minutes before each hour is over to give you enough time to accomplish the micro-step goal.
Pro Will fit almost any wrist size
The Alta is available in three different sizes (small, large, and extra large). Each size can be adjusted by a minimum of 1 inch.
This is a great tracker for people with wrists below or above average size who may have trouble finding a comfortable fit with other trackers.
Pro Lightweight and comfortable to wear
As a result of the Alta having a slim design, it is both lightweight and very comfortable to wear.
Pro Week long battery life
The fitness tracker's battery can last a full week before you need to recharge it - quite a bit longer than most activity trackers.
Cons
Con Might cause skin irritation for some
A number of people are reporting the Surge causes skin irritation. According to the company it's a very small percentage of customers.
Con Screen prone to inadvertent touches
It's really easy to accidentally brush up against the fitness tracker's watch and end up on screens that the user wasn't intending to navigate to. This forces you to swipe back to the correct screen.
Con Fairly big investment
While it's one of the most advanced trackers that Fitbit offers, it comes with a hefty price tag.
Con Fairly basic features which limits the information you'll receive from the tracker
The Alta fitness tracker is designed to be more of a passive tracker for the Average Joe as opposed to a complete activity tracker for enthusiasts. There is no GPS or heart rate monitor, so the stats you get are limited to steps, rough distance traveled, estimated calories burned, active minutes, and sleep tracking.
Con The device cannot be used without a smartphone or a computer
In order to activate the device for usage, it must be paired with a smartphone and/or a PC (through a USB dongle), and an account must be registered through Fitbit.
Con Difficult to see the display when outdoors
The display is quite dim which makes it very difficult to read when in bright settings.
Con Display is off by default
To manually turn on the display you must double tap the side of the tracker which can be difficult to do properly.
It can also turned on automatically by the appropriate wrist/arm movement for checking the time.
There is no way to keep the display on so it may take some fumbling every time you want to look at the display.
