The product is great and I am using it to measure intensity of exercise (mainly cycling). Monitoring intensity and duration is helping me to achieve my weight target. My only worry is where to get spare strap and/or transmitter if the present one becomes unusable.

Pls note that calorie consumed indicator by this instrument is very approximate and gives incorrect values if you are taking any medication for hypertention.

if your need is just to train within certain HR zone this is a great, no frills HRM. Easy to use and set zones and works accurately. one month into using battery still working..
something every person who's starting to train for distance running or triathlons should own

Cons: no GPS, pedometer compatibility
HR sensor is only 30 m Water Resistant
