'ACCURATE AND RELIABLE, EASY TO GET USED AND USE.'
Strengths: The speed and distance measure is very accurate. I have ran several half marathons using mine and it measures around 12.9, so its accurate. The calibration of the product only takes a few minutes and is fairly straight forward. This runs generally with the easy to use functions of the watch. You can have various different views of data as you run and can switch easily between them. You can also chose to manually make each lap or automatically mark times for each mile or KM (which is very useful). The footpod makes no difference on you foot as it is very light.
Weaknesses: The battery on the heart rate monitor seems to run out very quickly. The belt for the heart rate monitor is not as comfortable as the polar ones but by no means uncomfortable.
Overall: A useful training tool for those who do not know the distances they are running and who find it hard to judge pace. Its very easy to use and importantly accurate.
