I've had the fitbit charge HR for since this summer and I really like it. HR seems to be accurate to the HR monitors on the cardio machines at the gym. I like the other features of the fitbit...steps, distance (not GPS but based on stride), sleep, etc. A neighbor just received a Polar A300 (I think that's it) and she really likes it.

Have had great improvement or total elimination of: migraines, bloating/distention, heartburn, cystic acne, canker sores, bleeding gums, eczema on elbows, dry skin and scalp, muscle cramps, PMS, hair loss, heart palpitations, fatigue. I'm amazed.
