Tested with other oximeter, values are OK (aproofed by FDA)
Vibration and Sound test for high or low value of oxygen (only low) and puls, OK.
Great battery time. Work to gether with smart phone. High price but unique functionality.
This little monitor does the trick. It is not that intrusive so it doesn't get in the way of my arm moving at night, but the sensor also stays put (been using it for about a week now and haven't had it come off). The software for the smartphone calculates numbers like the amount of time the saturation is >95 and the number of drops 4% or greater during the measured period. With the software for the computer, you can save this in report AND data exports to allow you to analyze to your heart's content.
I brought this item and fell in love , why because is very light and you can see the oxygen informacion in his own screen or your phone for bluetooth.
But the best here is the service people was very polite and kindly with me.
Pricey home use medical device! It appears the FDA concluded that this medical device is a safe and effective product as a legally marketed device. Unlike other oximeters, it is unclear why the product or software does not document or record the perfusion index (PI)—a simple explanation may provide clarity. Concerned that one area of the rubber thumb band wrap may not be durable. Must be very careful taking thumb wrap on and off. The area of concern appears thin; may be weaken and break after minimum usage. Then the user must purchase a replacement cable for an already pricey product. The medical device performs as advertised.
