    First Fitness Tracker Purchased

    This was the first fitness tracker I have purchased and overall I find the information useful. It provides helpful data when tracking aerobic activity (running), quality of sleep, and calorie intake. If you like data this is definitely a useful tool. I have been somewhat disappointed in the Fitbit due to a couple of reasons. Primarily due to its reliability. My first one which I charged and then wore for a week never would charge again. Customer service was very helpful and sent me a new one fairly quickly, however, I am concerned that this maybe a significant issue with this item. In addition, I was hoping that it would be easier to input other workouts and activities. While I knew it would not track swimming I was hoping that you could input this activity directly into the app but the input only tracks running using your location.

    Fitbit is a great product for those looking for a general activity tracker. It is not super accurate but gives a good enough reading to keep you motivated. Unfortunately it registers random activities, like hammering, as taps and will put itself into sleep mode. I do love the sleep tracking feature though!

    We bought 2 Fitbit Flex fitness trackers. One for my husband who is 6'ft 3 and one for me (5ft ). We thought it would be a fun way to track of our daily activities and evening walks. Our route is exactly 3 miles. It said my husband walked 4 miles and I walked 2.5. I adjusted height and stride info and tried again with the same results. We returned both trackers.

    Overall this is a descent product, but I wish I would have spent the extra $25 dollars for the Charge model. I got one for my wife as well. The first one we got didn't work at all right out of the box. The one we replaced it with only holds a charge for about a day. Often goes into sleep mode when vibrated by things like pushing a shopping cart in the parking lot.

    Easy to use once you figure out need to download app first since comes with no instructions. I love my Flex as it makes me aware of my water intake and sleep and rest. It challenges me to get up and move every hour and achieving workout goals. I already feel more fit in just 3 weeks! Also have a more positive outlook on exercise. For me it helps make exercise more fun.

    My wife has tried many fit apps programs and gadgets and they all prettymuch were worthless. Until I got the fitbit wristband for her and I can say it was worth buying it. She loves it, it helps her track her steps, activity, calories, water intake, and sleep pattern. Only one minor complain the battery fully charge lasts a week before you need to charge it again. But it those charge quickly.
