Compact and easy to use with a color display and the ability to steer.
The analysis software is convenient and gives you the ability to record your results over a period of 24 hours.
There is a high and low alarm function, which allows you to preset oxygen saturation and pulse limits for audible and visual alarms to trigger.
I enjoyed the storage or transfer data in "real time" PC software.
excellent lifespan of the battery is also charged arrived.
Can we trust such a device? I do not have the opportunity to compare it with a medical professional unit. I rather think it can be used to collect data on its state of form in connection with a sport but it will never replace a real medical analysis.
