is the perfect partner to the polar heart rate monitor watch and does exactly what you need it to.
good for any exercise - weights, running, cycling, swimming.
can be slightly uncomfortable when sitting down but other than that just make sure you dont loose it too often as 3 in 6 months gets expensive to replace.
