Strengths: Downloadability, built in heart rate monitor saves carrying 2 evices
Weaknesses: Only draw back strap pin comes out on occasions, velcro strap can snag on technical tops.
Overall: Fantastic tool, it keeps a good running diary going for me, controls my heart rate to the point it even indicate the onset of flu recently, the virtual running partner is a great training aid and I would be lost without it.
