I debated on a fitbit for years. I don't know what I waited so long. My main exercise is walking and light running, so I didn't need all the bells and whistles. This was perfect. I love that it tracks my sleep (I thought sleeping with it on my wrist was going to bother me, but it doesn't) and allows me to enter my water in take. All I need now, is the different color bands.

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!

It is easy to use and accurate. I'd like it to measure my exercise more but minor.

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.

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.

Love this tracker. It works just as advertised the tracking app is easy to set up and sync. Comfortable and the band is great too. Wonderf customer service and support. I contacted them to see if they sold a band larger than the large one it comes with. They sent me an cl band at no charge. Pretty cool.

I am having the best time with my Fitbit & find I am exercising much more. I wear it all the time except once a week I do have to take it off to plug into the computer to recharge the battery. It records every step plus it tracks your sleep. It does synchronize online so you can record your calories & allows you to see calorie intake versus calories burned. I am truly very pleased with the purchase!
