'PLEASE NO MORE UPDATES IT'S COSTING ME A FORTUNE'
Strengths: Light, excellent signal particularly in wooded areas,software excellent and can purchase MB at relatively cheap price (I paid £24 per disc for Tracklogs to use with my 301).
Weaknesses: If you run with arm by your side tens to lose HRM signal, buttons stiff, expensive, appears not compatible with Tracklogs so my 3 discs at £24 each are now wasted.
Overall: I was happy with my Polar 610 and my 301 until I got this machine. It does everything you want and could probably do more if you have the time to explore it.Easy to go through the menus (certainly easier than 301).
