'ONE OF THE BEST RUNNING ACCESSORIES I HAVE PURCHASED.'
Strengths: Lots of functions and easy to use. Im now in my third year of use and done some 3,500 miles on it with no problems at all.
Weaknesses: Can lose signal in heavy tree lined areas.
Overall: A great piece of kit to assit your running. Helps keep a steady pace and measure those long runs - so no cheating. Love the training assistant too. Can now be purchased for under £80 if you shop around.
