Fitbit

I bought a garmin Vivofit and used it one day. The online and mobile software was a pain to use. I spent an hour on the phone with their customer support trying to figure out how to use the software. the numbers I got from it made no sense. I took it back the next day.
I got a fitbit zip to replace it and I love it. The online and mobile software is very easy to use and very intuitive. It snycs well and I am very happy with it. I am thinking I will upgrade to the new fitbit surge or charge, but I am going to wait until they have been out a while and I can see the reviews.

I bought a Flex to help me slow down loss and move on to maintenance and it's nothing less than amazing. I'm +- following it's adjustments to my daily calories for three months now - oscillating within a kilo around my target 75. Tremendous help with tracking all cardio based exercises (except biking etc obviously). Recommend waiting for the recently announced Fitbit Surge though - that indeed is an ultimate tracking device/smartwatch.

I love my One and would never go anywher without it. I have definitely walked more since I've had it and I would recommend it to anyone. The new models look pretty good but I personally prefer not to wear a wrist tracker for steps,purely because I don't think they are as accurate as one I wear on my waistband each day.

I have a FitBit One. I have found that I like to make sure I get to a required number of steps so that means I have to move more. The dashboard is good and clear and it does sync well with MFP. I use MFP to log food and leave the exercise element to FitBit. If you do cycling, I've heard that FitBit doesn't register it so well but I've also heard that you could tie it to your shoelace (or put it in your sock) so that it would register it as steps. Hope this helps a bit.

I've had a Flex for about a year and a half and to be honest, I don't really like it or find it useful. The LEDs in my first Flex started burning out in less than 6 months of using it which made it difficult to guess at how many steps you've put in. I stuck with the somewhat working lights until the band disintegrated. I was able to get it replaced very easily just by contacting Fitbit and telling them what happened. I've been using my replacement Flex for maybe 3 or 4 months and while the lights still work, the band on this one has cracked in numerous locations and is about ready to just fall apart completely. They are prone to breaking around the plastic display as that's how you remove it to charge. Keeping this in mind, I've been extremely careful when removing it hoping to prolong the lifespan of the band. I've even go so far as to remove it whenever I'm doing anything which could cause damage to the band. From what I've seen, the newer models have a significantly improved charging system that does not require removing the device from the band.

Since the Flex only has a series of lights, you have to guess at how many steps you've taken throughout the day based on the number of lit lights. At least they make it somewhat easy to guess based on the rate that the light blinks, but it is only a guess.

I guess at this point, I like it more as an alarm clock than anything else.

I have the fitbit one. It is cool, but check out the fitbit surge, which is out early next year.

It will track your calories in real time using an optical HRM to give you a more accurate burn rather than being step based. This is what i'm holding out for!

I've had the discontinued Fitbit Force. At the beginning it really did help to see how inactive I was. The software works, however if you ever want to do advanced data analysis you have to pay for their premium membership. Additionally Fitbit has stated they have no interest in syncing their data to Apple's new Heatlhkit app which is really annoying to me and goes back to the cost of the premium membership. At this time the battery in my Force is dying and I will more than likely be asking for a refund.
