So here is what I like about the flex: I like the way it looks on my wrist. All of us got the slate color. You can also order bands in a few different colors, both here and on the Fitbit site. It is lightweight and even though I don't often wear a watch I don't notice this on my wrist at all. The clasp was VERY difficult to secure the first couple of times until the rubber softened up a bit and until I got the hang of it. I secured it off of my wrist a couple times when it was new. Making sure the band and clasps are lined up correctly and then placing one finger directly below the clasp and my thumb directly above and squeezing hard was the way to do it.Read more ›
Here are my pro's and con's:
Sits nicely on your wrist and is comfortable and unobtrusive.
Quick indication of your planned "steps" for the day.
Great app with continual bluetooth connection - this is the best out there.
Doesn't need to be removed for bathing.
Tracks sleep pretty effectively.
You can integrate other data (BP, food, water weight etc.) on the web site. This is a novelty when you first start out but who seriously has the time to do all this?
Water gets in the bracelet and it gets gunky in the strap.
Unpredictable tracking of movements - it tracks cycling but for no logical reason and not accurate so it throws the figures way out. Same for cross trainer. Same for typing.
Battery life is short - 4 days max for me so far.
If the battery goes flat you lose all the unsynchronised data - easy to do if you're not near a charging point and I don't think there's any indication on the device that it's going to fail - you have to refer to the app.
So, I'm unsure about it. It's as good if not better than any of the others out there but it's really not much different to the old fashioned pedometers.Read more ›
I already had a fitbit zip which was good but the amount of times I left it on the bedside cabinet meant days went without any tracking. so I thought the wristband would be better for me.
I use the large band and I'm happy that it's comfortable (if not the easiest to put on with one hand - but it won't come off) and I forget it's on my wrist.
I like the sleep tracking function - it has shown me what I already know - I'm a restless sleeper - but no advice on how to change that!
More so that anything else I set a target number of steps on my iphone and throughout the day give it a double tap and see my progress. I've yet to not achieve my goal as I find myself quite competitive and don't want to be beaten by a machine.
The up side of that is I'm spending more time with my dog out long walks and after 3 weeks of using it I've lost 6lbs in weight. my overall goal was to become more active and fit and as a result I knew I'd lose weight but I didn't think it would be that quick.
the iphone app is ok but the web dashboard is much better if you have the time to log in to it. the graphs are more detailed and easier to follow online. there is a fitbit premium service you can join for £39.99 but I did the one week trial and couldn't really see what all the fuss was about.
the flex is well made and easy to use and it's great if you can get your friends into a fitbit - you get a progress chart on your phone and it constantly updates showing who is in the lead for the week with the total number of steps - another great way to get motivated.Read more ›
