Deluxe SM-110 Finger Pulse Oximeter with Carry Case and Neck/Wrist Cord...

I started out looking for a Heart Rate Monitor (HRM) and ended up testing these 3 items. Over the course of a few days, during simultaneous tests (at rest & during light workouts), their readings were so indistinguishable from one another that I cannot honestly declare one better than the others. In that respect, all three are very good. All three use Finger Pulse technology, so no straps are needed. Here are some observations that I hope will help folks make an informed decision: 1- The Omron looked stylish from the picture on ZeeBooth, but in reality, looked like an oversized, clumsy toy to me; I also did not like the digital display (the font style); Timex looks more graceful, and the display is better. 2- The Omron shows just the Heart Rate whereas the Timex shows not only the Heart Rate, but also the Relative Heart Rate (HR / Max. HR), and whether the HR is within the set Target HR Zone, over it, or under. That is nice. 3- Both watches have calories burnt feature, and stop watches; but Timex also has a Countdown Timer, and a second Time Zone (so one can set up clocks for 2 different parts of the world) 4- The night-light in the Timex also seems better to me, compared with the Omron 5- Omron uses two fingers for measuring HR, while Timex uses one. 6- Timex offers 2 sizes, midsize vs. fullsize; I recommend fullsize, because the display is bigger and much easier to read during any activity; seems more like normal to me, than the impression that "fullsize" conveys; and its cheaper than the midsize. I would have called them standard vs. small. 7- During setup, Omron does not incorporate gender, while Timex does; it's not that important but helps in setting up Target HR Zone. 8- I think that the Finger Pulse Oximeter SM-110 is good for the whole family; the user setup on the watches ties them to the wearer, while the Oximeter does not need any setup; it will dutifully do its job, and can be used for family fun and health; of course, it also shows the Oxygen Saturation level; and it comes with a carry case and neck / wrist cords. 9- FYI, the Activity mode on the Timex shows many more calories burnt than my Schwinn Exercise bike (almost 200 cal. difference on a 45 min workout); don't know if my bike is under-reporting, or the watch over-reporting. Overall, I think the Timex is a much better value for money than the Omron. Also, it goes without saying that these devices should be periodically cleaned to get accurate readings, as explained in their respective manuals. I'm keeping both the fullsize Timex & the Oximeter.
