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

In this uncertain Covid era, we learned it was wise to have an Oximeter on hand to measure oxygen levels. As I started to research, I immediately discounted brands new to the market since the onset of Covid-19. Instead, I found two that had many longtime reviews from satisfied users. Two stood out, the Zacurate Pro Series 500DL and the MiBest Oximeter. To my surprise, virtually everything was sold out and I thought I’d struck gold simply by scoring a MiBest after it was almost always out of stock. Once I’d ordered the MiBest and delivery was delayed, I found the Zacurate and ordered it, too. Which is best? See the photo above with Zacurate in black at left, and MiBest at right. One thing to know up front is that prices are skyrocketing for finger oximeters. They are suddenly hot items on the market. Some quick research showed that the well regarded MiBest had been selling for $30 for years, but at the time of this review its price is fluctuating between $50 and $55 when purchased directly from the company. The Zacurate has always been priced at less than $30 and I felt lucky to score one to compare to the more expensive MiBest. As it turns out, the Zacurate came a week faster than the MiBest. Simply put, it’s fantastic. Is $30 too good to be true when others can be $50 and up? I truly applaud Zacurate for not taking advantage at this time of tight finances for many in need of reliable health monitoring. It comes with a useful manual yet I learned the most from quick Internet research, such as normal health oxygen levels are between 94-100 and levels lower than that but still above 90 are normal for others. If your reading is under 90, consult your doctor. The Zacurate is consistent for both oxygen and pulse readings. Place it on a flat surface, stick your index finger in, bottom side down, press button to turn on unit and wait 5-6 seconds for the readout. When the MiBest came a few weeks after I ordered it, we were already 100% satisfied with the Zacurate. It does not include much documentation but also works well and has consistent readings. If you feel you must have an oximeter in hand ASAP, and the MiBest is available, I do recommend it yet am disappointed its price at $50-55 has nearly doubled. If you can find Zacurate available, and it costs less than the MiBest, it’s the clear first choice. It’s a trusted and very easy to use oximeter at a great price for home users like us, and medical professionals, too. Its readout is vertical, just as your finger will be. Thus, it's easier to read than the horizontally oriented MiBest. I hope this long review has been of some assistance and wish you and yours good health and strength. We believe better days are ahead.

Exactly what I needed! Currently have my first case of Covid in 2026 and started panicking when I feel like I couldn't take a deep breath. I ordered this and paid for rush delivery, it got here in under 2 hours. It's perfect, comes in a small compact box and includes the 2 batteries needed. Popped them in and had it on my finger within a minute of arrival. It turned on right away and worked immediately. The display is large and bright and easy to read. Simple to use, just push the on button and give it a few seconds to normalize. It gave me piece of mind that I was having a normal symptom and that my stupid anxiety was just making it seem way worse.

I purchased this oximiter when my mother went on hospice. The oximiter was reading a little low compared to the readings the visitinig nurse was getting, but the readings are consistant and repeatable and that is the important part. It is super easy to use just turn it on, wait until the numbers come up then clip it on the finger and read the bright and clearly labeled display. We are using it to identify large changes in oxygen levels and is working great for that

Very well made. Works well, no complaints so far.

I am happy with my purchase. It appears to be reading accurate and is super fast. It's lightweight and fits comfortably on any finger. The screen is bright and easy to read. I think it will be very beneficial to now be able to track everything myself at home. The price was very reasonable and I highly recommend every household has one on hand.

I am very impressed with this pulse oximeter. It is simple to operate, gives readings within seconds, and the large LED display is bright and easy to read. I especially like that the display is positioned so I can see the results without having to twist or reposition my hand. The finger chamber accommodates a good range of finger sizes and feels comfortable during use. The readings have been consistent and easy to monitor, and the device is compact enough to keep readily available when needed. Including the two AAA batteries is a nice convenience since it can be used immediately out of the box. The straightforward design, quick results, included batteries, warranty, and technical support make this an excellent value.

Works great!

The Zacurate comes bundled with the required batteries, and a helpful instruction booklet detailing precautions, maintenance, troubleshooting, and operational use. Even though the device is small, the LED display shows numerical readings in a bright red color large enough to be easily viewed. The readings on this pulse oximeter seem accurate after multiple uses. According to device specifications, accuracy on SpO2 readings ranges from 70-99%. Accuracy on pulse rate readings is plus or minus 3 BPM. The readings appear quickly in about five seconds. The device is inexpensive, but feels structurally robust considering the price point. It doesn’t seem it would fall apart anytime soon. This is a functional, light, and portable solution for tracking your oxygen levels and pulse rate.
