I am not a medical professional. The first thing I've tested it was accuracy of heart pulse bar indicator. I've palpated artery on my neck and compared it, found it was surprisingly accurate so BPM can't be inaccurate. Next I've tested spo2 and BPM by holding my breath/exercising while the oximeter was on my finger and values did not changed until I started breathing normally, from that I conclude that when those values rise or fall quickly it's delayed for 15+ seconds. On the opposite, when I took it off and did the same and then put it back on and measured, the change in those values before and after was clearly visible quickly. I believe that due to lower processing speed it cannot display live big changes in values in real time when device is constantly put on (measuring). Beside all of it this device feels comfortable on the finger due to the rubber material and provides a nice grip (spring is good as well as joint). Conclusion: To get the accurate live values, do not keep device on the finger constantly but take it off and start to measure again. I recommend and find it to be good value over the price you pay.Read full review

Very cooperative agent. Good quality for its price. Easy to operate. Light and comes with nice bag. The pictures are acceptable and the adjucment of gain and clarity is easy. Comes with almost all measurments like urology, gynecology and cardiolgy. No delay.
