Strengths: Inexpensive monitor that records average, maximum and minimum heart rates, and exercise duration. It is the only inexpensive monitor I am aware of with this combination. Comfortable transmitter with replaceable battery.
Weaknesses: This monitor has a probable design flaw. I tested 2 Cardiosport GO monitors that were manufactured at different times or in different factories (very different serial numbers, packaging, transmitter color, and one included a handlebar mount and one did not). Both had the same fatal flaw when used with a handlebar mount: they instantly stopped working when exposed to full sun. If you wave your hand back and forth over the face of the monitor on a sunny day, the "beating heart" icon will instantly turn off in sun and back on in shadow. The problem is unrelated to temperature: I live in a cool area (Wisconsin) and observed it at 50 degrees F as well as at higher temperatures, and it turns off much too fast to be heating up. It is also unrelated to the transmitter: conductive creme on the electrodes did not help, the Cardiosport transmitters worked perfectly when tested with a different-brand monitor, and the Cardiosport monitors displayed the same problem when tested with a different-brand transmitter. I contacted the USA distributor for Cardiosport about this problem and have not yet received a reply after approximately 3 weeks, which increases my suspicion that it is a design flaw. Nashbar has given me a refund for both monitors (they are a very reliable company in my experience). They said that they have gotten quite a number of returns, but that no one had described the full-sun problem. However, I suspect that if users who are experiencing the same highly frustrating erratic operation that I did were to perform the "hand-waving test", they will discover the source of the problem. Please note that the monitor works perfectly when there is a thin layer of cloud cover (muted shadows), so the test must be done in full sun.
Bottom Line:
If you buy one of these monitors do the hand-waving test I have described and if it fails, return it for refund.
