  • Best activity tracker I've tried

    4.0 out of 5 stars

    This tracker is very easy to use and the interface with ios7 is crisp and well designed. The only reason I didn't give it 5 stars This tracker is very easy to use and the interface with ios7 is crisp and well designed. The only reason I didn't give it 5 stars is that the bracelet has a very limited life span: it doesn't stand up to even the minimal wear and tear of gently removing the tracking element every few days for recharge, and I can see that I will need to replace my bracelet after only a couple of months. The tracker and charging cable are still fine and this isn't a major drawback as the replacement bracelets aren't that expensive, but they also aren't available everywhere.

    I had the Zip, but it just didn't generate enough information. The Flex has a great online app and links to a variety of apps, i.e I had the Zip, but it just didn't generate enough information. The Flex has a great online app and links to a variety of apps, i.e. MapMyRide.

    The wrist band takes a bit to get used to and locking the clap can be a challenge until the holes in the band loosen up a bit.

    One thing it doesn't do is track cycling. I remove it a put it in one of pockets but it doesn't quite do the job of recording the miles or steps. It also doesn't do steps.

    It's worth the money if you are looking to get a handle on your level of activity.

I also like the sleep function and it helps me keep up with my walking and excercise. I don't know to much about the Nike band, but I would not trade my Fitbit for anything.

  • Fell off and lost in two days! Won't sync w/ ipad/phone

    Got this as a present and set it up in 10-15 minutes. Downloaded fitbit app on ipad and iPod but after 4-5 hours of trying, I hadn Got this as a present and set it up in 10-15 minutes. Downloaded fitbit app on ipad and iPod but after 4-5 hours of trying, I hadn't been able to sync it to either of them. Horrible clasp! It fell off in my sleep multiple times. Fell off today and it is gone. Lost forever. I owned it for two days. You'd think a clasp made for exercise/activities wouldn't come undone when someone is sleeping let alone average daily activities. I'm sure happy they got their 100$ of my moms hard earned money though. What a horrible experience.

  • Excellent Tracker / Worst Wristband Ever

    1.0 out of 5 stars

    If you decide to take a chance on this tracker, be prepared to replace it OFTEN! The wristband is horrible. It is next to imposs If you decide to take a chance on this tracker, be prepared to replace it OFTEN! The wristband is horrible. It is next to impossible to get the two pronged clasp to insert into the band and even when you think it is locked in, the clasp will open unexpectedly every time you take your eyes off of it.

    The whole point of going for a wristband solution is so you don't have to think about which piece of clothing you last left your fitness tracker in but with this one, you'll be constantly worrying about how many days before it goes missing and you have to decide to spend another $100+ to replace it.

    The community forums have tons of people that have complained about this since the Flex came out and I only wish I had found all the complaints before I wasted my money on this device.

    Wait until Fitbit actually decides to put out a band that isn't going to constantly fall off every time you walk out the door which could take decades given the lack of feedback you see from the company itself regarding the large number of complaints about this terrible wristband.
