It would appear that the heart rate monitor is merely connected to a motion sensor, and that in response to the direction in which you pull it, it will either push or pull in the appropriate direction. I squatted thirty times without a device, then I put it on, and it gave me a resting pulse in the region of 70, or vice versa, you lie down on the couch, let your wife shake them for a minute, put them on, and voila, the pulse is 145. Both of these scenarios are possible. By donning some sweaters on top, the pulse is immediately visible. To sum it up, it's a toy for kids. I didn't believe the unfavorable reviews because I thought there was no way such a large number of people could be misled. I suppose it's a good thing I waited until the tsenik falls, because then I didn't waste nearly as much money. I indulged the child by giving them the item.
