Strengths: Easy to use & understand, has a back light, nice comfortable strap
Weaknesses: The back light is blue, would have been better in orange of regular light. The actual numbers are a bit on the small side to view at a glance when running. The silver face with all the functions on has worn away quickly.
Overall: A good all round piece of training kit, if they sort out these little niggles I have, I would be very happy with it
