    Although different from the image provided (which is the one that comes with the actual Garmin watch, the one I am replacing), it works perfectly. It's actually nicer looking. Very high-quality strap, comfortable fit, easily adjustable... won't move at all. Love it.

    Works great
    Works great with Garmin 500 bike computer. The one time it worked intermittently was because I did not wet the HR monitor enough. Pooring water from the tap did the trick.

    Does the job, but not going to win any awards.
    it does what it's supposed to... but for how long? I seem to need a new one every 8 months or so, and I follow the "care" directions to a T. I bought one, and it was defective out of the box...

    This belt has no problems with measuring heart rate, which is why I bought it. It has, however, a fit problem. No matter how tight I make the strap, it inevitably loosens up on a run and slides down. I don't know why it does this as the cheaper version of the belt does not.

    It is more comfortable than the previous generation. It could use something grippy on the strap though. The front, where the sensors are stays in place, but the back tends to slide down my back, even when overly tight.

    Works without skipping a beat
    It works as it should, just wet the spots on the back, put it on and start your gadget within 3m's of it and it'll show up.
