After looking at several different heart rate monitors I decided to go with the F6. I could not be happier! It comes in the color pink for the ladies and fits my small wrist. One of the best features I like is that it also doubles as a wrist watch so I don't have to wear a watch on one wrist and a heart rate monitor on the other.
The only issue I had with this heart rate monitor is trying to figure out how to upload your workouts to your computer. But once you figure it out you get really great readouts on the computer and can keep up with your daily, weekly and monthly workouts. I highly recommend this product.
