With tele-medicine increasingly used in this COVID-19 era, I decided to get this pulse oximeter, plus a blood pressure monitor (sphygmomanometer), to use at home. The % O2 readings given by the 500DL are very close to those of the medical grade blood O2 device at my MD's office.Long term accuracy and reliability are to be determined but I'll give it an initial 5-stars, in part due to value.

I bought this as a second one to compare with another more expensive Oximeter. I wasn???t sure if my first one was correct since it usually indicated 88-95. This one averages about 1-2 points higher.However, this one does not let you invert readout so your can switch hands and still read it without twisting your head or arm around. This one does record to app I installed on my iPhone which is hand...

Nevertheless, a neat daily device to ...

I've used several of these oximeters and I like the way this unit has a more stable readout as it updates the display. Other units update and change a bit too frequently. Maybe they have a faster sampling rate. This unit seems to have a better edge on more stable and accurate data in the display. I also like the ability to have the collected data recorded and a basic report computed on my smartpho...

The oximeter is very easy to use and read. I could not comment on accuracy as I have nothing to compare it to. I find it a little off putting that if I test four different fingers in a row, I get four different answers. I suppose some of my fingers are "harder" to read than others. But, since I never see the nurses try another finger when they use it in the office, I guess they just accept the...
