Fitbit Blaze – Review

When the strap of my Fitbit HR started bubbling for the second time (it was replace just under a year ago for the sane reason) I swiftly contacted the company who were only too happy to offer me a like for like replacement, however they also offered me a discount on one of their newer models instead. Now as someone who walks a lot I always like to keep track of my miles/steps but it has become more important with my 2500 miles in 2017 challenge, so I wanted something that would do that but would also function as a stylish watch (if you’ve read my other reviews you’ll know I like to look good on the footpaths of Britain). The Fitbit Blaze fitted both of those options, so I opted to take a 50% discount instead of a replacement for the HR.

Now I know wearable trackers are not for everyone and there are inaccuracies in their tracking at times etc. but before I start I would like to confirm it is calibrated to my average stride length, and I have tested its accuracy on counting my steps (you’ll see later), but as with all my reviews here are the technical specs first.

I hope Fitbit won’t mind me lifting this off their website?

Personally I like the design, although I know this can be subjective, I don’t find it too large on my wrist, although a thinner “wristed” person may (Zoe is not a fan, and thinks it would be way too large on her wrist), and the simple rubber strap works well with the metal housing. I love that there are other options available, the actual device clips into the metallic surround, and needs to be removed to charge, (Fitbit sell their own, or there are 3rd party straps for a lot less money), personally am thinking about getting a metal one and a leather (or faux leather) one so I can change up my look! Yes I do indeed think I’m a fashion blogger now.

The GUI of the watch (Graphical User Interface) is simple to use, with swiping left or right to scroll through the main menus or up and down for specific sections, and there are 12 different designs for a clock, both analogue looking and digital. The music controls work well with my iPhone, as does the call answering option and I do like being able to read my text messages via the Blaze rather than having to get my phone out all the time. So over all it is winning here.

Tests with Walking

I set my stride length with my old HR, so have not needed to alter this to get a pretty accurate reading, I actually loose a couple of tenths over the course of a mile, so 1 mile walked shows as 0.98 of a mile on the Fitbit (variances over rough and uneven ground do not seem much either). and when I paced out 100 steps I was getting between 97 and 101 showing on  the Blaze after the walk. So I am pretty happy that I am getting an overall picture of my distances and number of steps within quite a close margin, after all nothing is perfect.

I think little attention needs to be paid to the stairs count, I’ve never really known why it matters and it is certainly not accurate in reality, I’ve had massive over estimations (usually) and many under estimations, so would never suggest sing this as accurate. I also can’t vouch for the Fitstar element because I simply have not used it, it isn’t my thing. Although the Relax part of the watch (it walks you through slowing breathing) seems to work quite well.

The heart rate monitor seems pretty accurate but I don’t test my heart rate that often (if at all) but the Blaze seems to math up with the HR and Apple watch monitors.

Rigours of use

I’ve worn the Fitbit Blaze pretty much constantly since purchasing it (shows and charge times aside) and have found it comfortable and without much complaint, although there have been a couple of minor issues and I am a little worried that the screen my scratch if I knock it through the summer months, but I guess time will tell (no damage yet, the glass seems very tough and scratch resistant, and I’ve knocked it a few times).

Minor Issues

Stair counting aside, I’ve noticed two issues:Firstly battery life, which isn’t too bad (4-5 days roughly), but still annoying having to charge so often, especially if you find yourself away from easy plug sockets (camping without EHU).

Secondly, and this one is a pain, if you wear a long sleeved top and sweat a lot or it rains! Seems odd that last one right? Well I was caught out in some rain with only a hoodie (yeah and trousers!) and the sleeves got quite damp, this meant they constantly rubbed on the screen of the Blaze and kept jumping my music (well podcasts) as the wet jumper mimicked the effect of a finger swipe. Turning off the option for music control stopped that issue, but I have had timers switched on or exercise options activated these are quite annoying in themselves, but it also means that the watch battery ran down even quicker than normal.


So there you have it, it’s stylish and seems pretty accurate to me, has a few drawbacks, but then all activity trackers do. But I am glad I have my Fitbit Blaze, it motivates me to do more and helps track my miles.
