Best Fingertip Heart Rate Monitor.
This is the highly accurate heart rate monitor pulse oximeter that was also the easiest to use and the most comfortable in tests conducted by The Hammacher Schlemmer Institute.
While all units took pulse readings that were comparable to those taken by a registered nurse, panelists found that The Best model's gently flexing hinges provided optimal comfort on large or small fingers, unlike lesser units that pinched. It displayed readings on its high-definition color OLED display in an average of 7 seconds, 2X faster than lesser models that required 14 seconds. The display changes to your preferred viewing orientation at the touch of a button, and it can also announce readings in a clear female voice--the only model to offer this convenience. Also an oximeter, The Best model averaged only a 0.84% variance from readings taken with a clinical oximeter--far superior to lesser models that were off by 4%. Includes carrying case, lanyard, and two AAA batteries.
