    I like the fitbit so far. Wish it had more features. Very easy to use and the battery last a while. Bought the fitbit to help me stay on track with my fitness goals each day. The added advantage is that it monitors your sleep habits. I still don't know how accurate it is but would recommend.

    This is a great tool for the $100 price point. I feel it is pretty accurate and the lights that track your % to goal are fun to follow. The material that the band is made of is very comfortable and the small size fits my wrist perfectly. The battery has held true to about 5 days, as said in the product details. There are a few things that I hope will change. I have not signed up for the Premier program yet ($50 a year) and have just been using the regular Free application. There are many foods not listed in the food log. meaning, you need to manually enter each item. Also, you need to pay for the Premier level if you want to sync with any other application that would have a bar code scanner. Overall for $100 it is a good product. *I wish the other colors in the wristband would come in soon!!

    I use my fitbit to track my steps and my sleep. The social aspect is great because my friends and I all compete to make sure we are moving. It is easy to use on my iphone and you only have to charge it about once a week. The clasp is difficult to hook and I lost my first fitbit after 24 hours because the clasp got caught on my backpack strap and I didnt notice it had come off. :(

    Early birthday present for my 15 year old daughter. She has been working hard to get into shape for school sports and this was a present she had been asking for. It has truly motivated her to continue to stay healthy;she is always super excieted to get her 10,000 steps each day. Even though she is almost 5'10", she has a small wrist and we bought her the small which fits perfectly (the salesman tried to get recommned the medium)

    This is a great tool to get you motivated to get back in shape! It is a nice reminder all day to get your steps in and start moving, I didn't realize how much I was stationary all day. Only issues I have had with it is that it sometimes won't sync to my iPhone 6 (even with latest software installed) I have to just turn off my phone completely than it reads just fine, might just be my phone having the issue because computer Bluetooth piece syncs fine. Other than that minor issue, I love this product and truly had helped me in my health!

    Adequate step tracker. Enjoy the sleep tracker function. Comfortable. Wish the battery lasted longer. Heard Jawbone lasted 10 days vs Fitbit 5.

    Works pretty well, had a tough time and felt funny on my arm after wearing it all day. The sleep function was interesting to see but not sure if my fiance's snoring affected the accuracy of this tool. Instead of wearing it on my wrist I put it on my ankle which to me gave a more accurate step total in that I speak with my hands so when I would present all day it would give me TONS of steps but overall does well.

    overall, pretty happy with it as it's my first wearable tech device. It syncs with my phone via bluetooth and that's the most convenient. Nice that it can pair with a computer but unless you have a BT interface, you'll need to use the USB dongle. Seems a little pricey for what it does so that's why I didn't give it a 5 star.

    I bought this as a gift for my Wife for Mother's Day. She was very excited to use it and got it all charged and ready within the first day she received it. Then by the end of the first week it started to loose charge. She charged it again and then the battery died again two days later. Now it won't keep a charge at all. She likes it, so she will return it for another one. Hopefully she won't have to return that one as well.

    I don't like wearing a watch or bracelet but this doesn't bother me. It was a bit difficult at first to learn how to put it to sleep & then wake it up & do that properly for first few tries but then again I'm 61. I like showing my husband how often his snoring wakes me up! haha! Bit pricey for what it is. Battery lasts about a week.
