Specs
Question Ranking
Pros
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 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 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 Comfortable and secure
The elastic band comes in three sizes and is soft and malleable. The H7 sits pretty snugly against your chest and doesn't slip around while you're using it.
Pro Very accurate
The H7 was tested against an EKG, the medical standard for measuring heart rate, and it was found that the H7's readings matched up with the EKG 99% of the time.
You can see the accuracy tests here.
Pro Waterproof, so it's great for swimmers
The H7 is properly waterproof, making it a good option for swimmers. However, when underwater, your Bluetooth connection won't work so you're forced into using one of Polar's GymLink enabled watches.
Pro Supports a wide range of connectivity options
The H7 can connect via Bluetooth Smart or GymLink. It can connect to a wide range of apps (like Runkeeper, Runtastic, or Strava) and works with Bluetooth sports watches as well. The GymLink connection means it'll work with Polar's other sport watches or activity trackers.
Pro Long battery life with replaceable cell batteries
The H7 runs on a CR2025 coin battery which, as long as you disconnect the device from the strap when not in use, should last you upwards of a month before needing to be replaced.
Cons
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 Bluetooth doesn't work underwater
Unfortunately, the H7 can't communicate via Bluetooth when it's submerged. You'll have to use one of Polar's other GymLink enabled watches to get functionality while swimming.
