2.0 out of 5 stars not good for exercise, January 7, 2008

The monitor seems to be fine when the pulse was around the resting rate but can't keep up when the heart rate climbed with exercise. Can't blame sweating or finger movement as I was cycling indoors on a trainer and wasn't even sweating when the monitor started to lag behind. I even kept the hand off the handlebar to minimize any movement. The gap in reading was especially pronounced in the beginning as the heart rate rapidly climbed. Around the true rate of 50's to 70's the monitor seemed accurate. However, by 90's it was about 20 behind, and by 130, it was at least up to 40 to 50 behind. With steady exercise, the gap gradually narrowed, but at a steady rate of 150's the reading was still about 20 to 30 behind and then would drop down to 70 to 90s for many minutes. When my heart rate climbed to 160 to 180s, the reading became totally unreliable. I tried holding the sides of the ring to keep the sensor steady, using different fingers, and repositioning the sensor etc. but didn't make any difference.

The sensor and the light (infrared?) source are on each side of the ring and am guessing that they detect the change in light transmission through the finger as the blood flows through the fingers. The reading isn't instantaneous but seems to take an average or a reading every few seconds. It'd have been fine if the readings were accurate.

There is a reason this heart ring is getting bad reviews. It doesn't give a good reading when you exercise. While I was resting the monitor ring seemed to work fine, but when I started exercising it showed my heart rate went down from 80 to 40. When I turned the heart rate monitor on, it would stay on for a few minutes and then just shut off. The clock mode will only give you 24 hour time with no way to change to 12 hour time. If it worked as described it would be worth the money, but learn from my mistake and others. Look for something better. By the way, on the second day that I owned this heart ring I got it wet. I went and looked at the manual that came with the ring. No were did it say it was water proof, much less water resistant. As you might guess it stopped working, so I threw it straight into the trash were it belongs. This LifeSpan fitness heart rate monitor ring had a life span of less than 36 hours.

Heart rate is not correct. It is convenient, however, that this item has a stopwatch function, which allowed me to time a minute while counting my heart beats for myself and find out that it is off my as many as 50 bpm.
