    I find find that this product really motivates me to reach at least 10000 steps a day. I love the features and found myself realizing I wasn't sleeping as well as I thought I was.

    This fitness tracker is quite satisfactory with the exception of how difficult it is to put on - can be very frustrating. I don't want to sleep with the thing on, so I put it on each morning, and even after getting the knack of it somewhat, it still can take more time than I'd like to spend on it.

    Excellent device for tracking activity and encouraging one to do more. Limitation I've discovered is device should not be worn when mowing the lawn, hammering a nail, or other type activities that might cause it to give false indications.

    For the price, this is one of the best trackers. I wear this daily, I find it to be a good guideline. Like anything nothing is perfect. It has helped me get my steps in daily. The only thing I would hope for is that the battery would last 2 weeks. Not just 4 days. Charging doesn't take long.

    I like my fitbit flex very much. I tested its accuracy as a pedometer and it is within 1-3%, quite good!! I like how it tracks activity and sleep, too and the website and smartphone dashboard it helpful. The only problem with it is that I actually lost it in a parking lot after trying to get my keys out of my pocket. It must have got hung up on the outside of my pocket when my hand went in, causing the clasp to come loose. Noticed about 20 mins later while trying to move furniture. Luckily someone found it and held it for me. My solution: I added a safety tether by looping a small length of one of the strands from the inside of some 550 paracord between the two ends. It has saved it from being lost many times.

    I like it. Would have give it 5 stars, but have hard time getting it to go into sleep mode. The instructions are not good. Used pencil to rapidly tap it to get it in and out of sleep mode. I can tell when I forget to put it on. It's like another piece of jewelry. Don't leave home without it.
