I really enjoy the styling and quality of this oximeter. After debating buying from other online vendors, I settled for this one as it comes from this reputable site, and arrived quickly. It seems to work as stated. Comes with certificate of authenticity / calibration. This makes me think it is of a decent quality. However, it is hard to tell how accurate it is. Also, moving around seems to make the reading jump quite a bit.

Works for me. Just remember to firmly insert your finger all the way or the reading will bounce around. This is as accurate as others in this price range. It is accurate to plus or minus 2%. Just get a healthy benchmark for yourself and watch the trend line. Be aware if it drops too much from your normal.

Very glad to have received this so quickly and it came in handy just yesterday. Was confirmed by a nurse to be as accurate as more expensive ones

Good Oximeter and a must to have product nowdays. Easy to use and it takes continous reading.

a handy device when you need to take a test.
