Bests & Worsts Reviews from Amazon

I picked one up from Target. I really love it so far! I am a very active person and now that I'm pregnant, I know it is even more important to track my heart rate during exercise. I was a little hesitant to get one because I read several reviews where people were saying that the heart rate was inaccurate. I compared it with a manual heart rate as well as a pulse oximetry machine at the hospital that I work at and it was always very close in range-maybe off by 4-5 beats, which isn't a big deal for me. I like the silent alarm because a regular alarm scares the s*** out of me every morning. Also, it is cool that it knows when I go to sleep and showed me how many times I got restless thru the night! The other features are great, especially if coupled with the app, but they are just bonuses for me. I really wanted this as a heart rate tracker and liked it because it has a slim design.
