I've been using my FitBit Zip for a few weeks now, and I have to say I'm really enjoying it. I attach it to the inside of my pocket at the start of the day and don't have to worry about it until I take if off that night. The Zip is capable of accurately measuring your steps and also has the nice feature of telling you how many miles you've walked. It also includes a little face that will get happier with the more you exercise. I'm not sure what it is about that little face, but it gives me a really good feeling when it changes to a face with a tongue sticking out, to a face that is clearly the happiest face in the world. Apart from all of the cool features, what I like most about the FitBit Zip is that it can automatically sync to your computer and on the FitBit website you can keep track of your steps, calories burned, and many other things. If you are interested in losing weight or trying to live a healthier lifestyle, the FitBit Zip is for you.
