Pro Very easy to read, even in bright sunlight
The Fitbit Blaze is a great option for outdoor use thanks to how easy it is to see the display even in bright sunlight.
The clear and bright display uses plenty of color for better clarity.
Pro Wide range of wrist straps available for a more personalized look
If you don't like the basic rubber wrist strap the comes with the tracker, you can change out the strap for more premium options.
There are many different styles available including leather, silicone, or stainless steel in a variety of colors.
Pro Tracks your activity in a large variety of ways
The Fitbit Blaze fitness tracker is feature-rich and tracks steps, calories burned, distance traveled, active minutes, floors climbed, heart-rate, and sleep time.
Pro Long battery life for being so feature-rich
While it varies somewhat, many people have been reporting that the fitness tracker usually lasts 5 full days on a single charge.
In general, the more features a tracker has, the faster it will drain the battery. 4 or 5 days is an impressive charge compared to other trackers with similar features (continuous heart rate tracking for example).
Pro Interesting design
The Blaze has a techie look to it that some may find a nice change from the usual sporty-appearance of trackers.
It is fairly lightweight and the design isn't offensive, it's something you can wear every day.
Pro Gives you a lot of options for customizing different types of workouts
The "Sport Profile" feature allows you to customize what stats you want to see for each type of exercise. For example, you may want the GPS on for running but not for a circuit workout. These preset profiles save you from having to set up the device each time you exercise.
Pro Detailed reports
The fitness tracker offers excellent reporting including distance, speed, cadence, heart rate (if paired with monitor), ascent, decent, calories, recovery status, and more.
Pro Gives you custom activity goals suitable for your level
The daily activity goal is a good way to find out how active you really are in your everyday life. Here you can choose your typical activity level from three options and see how active you need to be to reach your daily activity goal.
The time you need to complete your daily activity goal depends on the level you have chosen and the intensity of your activities. Age and gender also affect the intensity you need to reach your daily activity goal.
Pro Ability to add training notes
The app allows you to add additional notes to your workouts for better tracking.
Con Poor use of the large display
The fitness tracker's screen takes up a small amount of the front face. The glass bezels and casing take up most of the front.
Con Requires your smartphone for GPS tracking
The Blaze lacks a built-in GPS so it can't track the route of your runs on its own. It can, however, be paired with your smartphone to use its GPS and track the route that way.
Con Inconvenient to charge
To charge the Blaze fitness tracker, you need to remove the main module and lock it into its charger.
Con Sleep tracking lacks detail and accuracy
If you are awake for an extended period of time in the middle of the night and then fall back asleep, the fitness tracker may not see the additional hours as part of your sleep.
Con Unattractive and bulky design
The tracker is quite wide and hard to miss, it's not something that can blend in with what you're wearing outside of sport/exercise type settings.
Con Short battery life when using the GPS
With the GPS turned on, battery life goes from around 24 days to 9 hours.
This is likely fine for people who will always have opportunities to charge it after their run. However for anyone hoping to use the GPS for longer activities, such as hiking, that may not be long enough to be useful.
