I've got a Vivfit by Garmin, which costs less. It tracks my steps, makes a rough calculation of calories used based on my steps and weight, lets me know how many more steps I should take based on the goal I set. it also monitors my sleep, gives me the time and date. The cons are that the face is not back-lit, the band is tricky to secure, and the instructions are not complete. I had to download instructions from the internet. Pros are that I'm moving more; the watch will work for a year out of the box without having to be recharged; syncs with either my iPad or iMac (and, I presume, iPhones, and probably Androids); tracks my sleep patterns. I'm highly tolerant of wearing a watch, even one with a fairly thick plastic band, 24-7, so that is not an issue for me. it was about $67 at BJ's.
