anyone heard of this device that measures your oxygen consumption and what not, then gives you the EXACT amount of calories you burn at a resting heart rate throughout the day. i know the caluculation to get this number, but supposedly that caluculation could be off by as much as 700cals sometimes. well i am able to get one for $700. they usually go for $1700. what do you guys think?
