Here is the “Power Glove” an unusual cardiofrequencymeter adapted for those who have problems wearing the strap around the chest (allergy etc. .).
It is true that there are heart rate monitors that can be put on the finger, but its often not really adapted to run or do sport… you have to stay still to use them. ..not so practical.

So, the real novelty with this model, is thanks to the glove you put on, which doesn’t risk falling off whenever you go running. It has access to the classical characteristics (profile, MHR, %, burnt calories, etc. ..) of a heart rate monitor.
You can buy it for $79.9 here.
