Zacurate Pro Series 500DL Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with Silicone Cover, Batteries and Lanyard (Royal Black)

Zacurate Oximeter vs. MiBest: Which is best in Covid era?
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.

Great product!
This item works well and it is very convenient. It takes two AAA batteries, which they provide. I’ve found the readings to be accurate and it comes in a nice little case. It has a string for people who need to check vitals often.

Excellent item
Excellent item. Fast and accurate. Easy to read.

Defo prefer spending extra for the OLED version, for 2 features
The pricier OLED version (tho by not as much as you think) has two features that makes this purchase worth it to me: the perfusion index and plethysmograph.If you have your fingertip misaligned with the LEDs, or have cold fingertips from recently coming in from the cold, or compressed arm / hand arteries for any number of reasons… the SpO₂ reading won’t be as accurate. Making sure your PI is as high as possible using the plethysmograph and index reading, increases SpO₂ accuracy.For medical professionals whose environment and patient postures can be controlled more closely w/ training, the cheaper version on a lanyard will defo be the buy to get for a nurse. But for layman-self here, reading on myself in a tropical climate… the OLED version tells me when my watch or clothing or posture’s getting in the way of accuracy — worth it.Recently diagnosed with a condition affecting SpO₂. This allows me to have empirical data to take to the doc’s office, in their own vernacular — a plus since many skilled professionals but *especially* medical pros have to dumb-down their explanations so often to the civilian, human nature dictates they’ll triage you rather than expend this extra energy. Skipping this step by giving them data points they use amongst themselves away from the patient (as well as you understanding what they mean) keeps the relationship more honest and less taxing for an overloaded, under-funded front end of an ER.Pros (OLED version):- perfusion index and plethysmograph indispensible for the non-medical-professional- great legibility, esp settings where you can adjust display mode and brightness (not possible on the cheaper version)- comes w/ silicone case (sorry for the people who’re hung up over how they look; just fine to me and already protected my oximeter in a drop, sooo 🤷)- comes w/ batteries- comes w/ a lanyard which is clip-removable, a useful touch (esp for a med pro)- exactly the same size as the non-OLED versionCons (OLED version):- 57% more expensive than non-OLED version (however, if you take into account reading errors from lack of the two above features, plus 57% more as of April 2025 means just $13… you can see where I don’t consider it a con)- possibly not as durable if screen takes impact — a segmented digital readout is just simpler and more durableFive stars, as have already used (and dropped) this oximeter a week now, no problems. Would buy again / recommend OLED version ⭐️⭐️⭐️⭐️⭐️

Very easy to use product

Quick response. Clear results. Had purchased a cheaper device as a backup while out and about (I have heart problems)… The cheaper device was a a dud, even after 2 minutes wouldn’t give a reading. This Oximeter is just what I need… Highly recommended. Don’t bother with the cheapies: unreliable operation…

Seems to be good quality product. I know measurements are reliable as my younger kid always had a little lower oxygen level, which this pulseoximeter immediately showed. Fits fingers of all sizes well.Everything is included in the package, including the battery. Usage is very simple, just put it on your finger and press the only button.Highly recommended, especially nowadays.
