Zacurate 500BL Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with Batteries Included (Navy Blue)ClimatePartner certified

This little device is super handy and surprisingly accurate. I like how fast it gives results—just slip it on your finger and within seconds you have your oxygen and pulse reading. The display is clear and easy to read, and it even came with batteries, which was a nice touch. It feels sturdy and works well for both quick checks and regular monitoring. Definitely a great tool to have at home for peace of mind.

I recently had abdominal surgery and was experiencing some difficulty taking in a deep breath so I went to the emergency room as anyone should of course --- all my tests came back normal, and my pulse-ox was in good range. More or less I purchased this as a backup peace of mind device for home use, so when I experienced that feeling, I could check and ease my feelings of panic. We're still working out what may be causing my personal symptoms, and while this is obviously in no way a substitute for professional medical evaluation and care, it is a great item to have on hand to measure an essential reading.I find that the readout is accurate, and I like that the side display light gets low bar or stops if the device is not placed correctly on my finger. A simple adjustment gets the readout going again. Do understand that this is a continual read device and doesn't give a final, static number.Couldn't be easier to use. I do recommend getting some quality AAA batteries to install, as the included batteries may have been sitting for who knows how long.Again ------ if you are using this for medical interpretation rather than athletic etc., ----- Please make sure you see your own medical team for proper treatment and documentation. Do not use home monitoring devices in place of professional care - ever.

Works great! Easy to use. Hang to own. Well built. Reasonably priced.

For the small price it seems to work well. I orinally thought mine did not come with batteries but I found them, they fell when I opened the box.

We got this to check oxygen saturation when wife is having asthma issues. On electronic devices I like to use them awhile before giving a review. So after about 3 years I thought it is time.With the information we get from this easy to use device we can decide on which method is used to alleviate symptoms or if medical advice required. It also will give ongoing heart rate while clipped to the finger which we use to check heart rate and recovery following excercise. This unit uses two AAA batteries and they last a long time. We have been using this 3 years and have yet to need new batteries.

Very erratic. I can't trust it to give me an accurate reading. I have two other types of Zac Vrate oximeters and this one gives me different readings than the others, most of the time. The Pro Series is the most accurate one that I have.Update: The seller, Beyond Med Shop, reached out to me and after a couple of emails back and forth they offered to send me a replacement. No only a replacement but they're sending me a different model at my request. They take good care of customers. I highly recommend them.

Easy to use and easy to read. Purchased this for my Mother-in-law.

Works great. Easy to use
