Zacurate 500E-B Wireless Bluetooth Fingertip Blood Pulse Oximeter Monitor with FREE App, SpO2, Heart Rate, Plethysmograph, and Perfusion Index Finger Oxygen Sensor Meter

This thing works great must have for a first aid kit.

It’s excellent and more accurate

So far, it seems to be working fine... I wish there was methods to check calibration of these new instruments to some standard.

Accurate meter just takes a few seconds to register. Love the pouch carrier.

I love this product. It shows oxygen, pulse, RR. I am very concerned.

Fantastic!Blue tooth allows a record and ability to monitor po2 for at home person with O2

This thing is close to being useless! 1st. Never mentioned that one has to avoid all pop up ads on app! In your face ads!, requiring one to answer questions before proceeding. 2nd, readings I get, once you avoid pop up ads, are not accurate! Why want this mentioned in description? Why no one else left a review stating ads? I don't know. Let's see if this honest review makes it through. Either I'm returning unit, or tossong it. I'll go back to regular cuff style. No ads.

Arrived on time in perfect condition. Had excellent feedback comments. I was a little wary as it was under $12. bucks to my door. I recently took this to my pulmonary walking test and compared numbers to the hospital's state of the art device. The pulse was the same throughout the walking test. The saturation number was low, BUT consistently by 3 points...so now I know accurately what my oxygen saturation is simply by adding 3 points. If you need such a "tool", get this one. Come with a protective woven nylon case so it's safe to throw in my backpack. buy without hesitation.

I was very pleased with the overall quality of the meter. It is well made, comes with a rubber cover for protection fro the elements and a very sturdy velcro closing nylon carry case. Also supplied is an easily fitted, strong lanyard. The instructions are easy to follow and simple, yet go further to in depth explanation of how the device functions and operates. The cradle for the finger is comfortable and I had no trouble getting a reading. It is accurate alongside other meters and very easy to read. It requires 2 AAA batteries, which were supplied in a sealed package. There are multiple read formats to suit most. The price is very reasonable and delivery was sooner than stated. It was packaged well and arrived in excellent condition. I would recommend this little unit to anyone who might have need for one. I am now more confident that I can assess my heart rate and blood oxygen saturation on a very regular basis.

Uso médico hasta el momento excelente

Works well, readings are accurate and battery seems to last a long time when the device is being stored between uses. Storage case is very sturdy. No complaints.

This is my second oximeter and appears to be accurate. Heart rate matches the reading on my blood pressure monitor.

This was purchased to double check my overnight readings using my Fitbit Versa 3.This is more accurate,and more specifically designed for SpO2 readings and at anytime of day.Highly recommend,as a very accurate SpO2 readings at anytime.COVID times and non Covid times.
