I have had a number of chest strap type heart rate monitoring sensors and have never used them consistently due to their discomfort and the strap fussing.
I recently purchased the $99 MioLink, a wristband that monitors heart rate. The MioLink is small and unobtrusive. It comes in 2 rubber size straps. I picked the large for my very small wrist and can't imagine very many people needing the smaller size. The sensor slips out of the back of the band so the band is replaceable, washable.
Mio monitors heart rate as follows: "Integrated into the back plate of a wristband or watch, the LEDs shine light into the skin, which enables the electro-optical cell to detect your pulsing volume of blood flow." So far seems to work fine and at long last the nasty strap is gone!
The MioLink can give you heart rate information in 2 ways:
- a blinking LED light with different colors indicating what heart rate zone you are in. 5 zones can be set in the Mio iPhone (4S and newer) app and on Android devices with Bluetooth 4.0. See compatibility list here. I have not found the blinking mode particularly useful on the run as the blink interval is about 4 seconds and who wants to stare at your wrist that long. For more stationary exercises fine. The second mode below
- as the MioLink has Bluetooth Smart 4.0 as well as an ANT+ it can communicate with phone run apps (iSmoothRun, Strava, etc...) which capture data such as heart rate using these communications protocols. I actually use iSmoothRun on an iPhone 5s and have the Mio data as well as my run statistics coming through that app to my Magellan Echo watch (review here), itself a Bluetooth Smart controller and display. It should also be able to send data to any ANT+ communicating device such as many of the Garmin watches and bike computers which used ANT+, etc...

Battery life is claimed to be 8-10 hours. Charging is via USB dongle. Water resistant to 30 meters.
