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

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.

This pulse oximeter works really well and is very easy to use. The functionality is simple and gives quick readings without any hassle. The display is bright and clear, so it is easy to read the numbers even in lower light. It fits comfortably on the finger and does not feel too tight or too loose, which helps it stay in place during use. The readings seem accurate and consistent, which is important for something like this. The battery life has been good so far and lasts a while without needing frequent changes. Overall, it is reliable, easy to use, and gives clear and accurate results.

Fast shipping, excellent quality device. Very accurate readings and easy to use.

I bought the first one April 2024. I had to replace it, and did so April 2025. Now it is suddenly not working. I changed the batteries, but it isn't that. So, I'm about to replace it, April 2026. It is an excellent device, and I use it a lot. Really heavy use. I like it enough to buy it again. However, I don't like the short lifespan.

I've been looking for a device to monitor my pulse, and settled on the Zacurate fingertip pulse oximeters. Actually, I recently bought the Zacurate 500BL for just 10 bucks and was so impressed with the quality of it that I upgraded to the 500C, and will keep the 500BL at work. Both devices provide a quick, easy to read measurement of your blood oxygen saturation level as well as your pulse. Both devices work on AAA batteries (which are supplied). This 500C model is a step up because the display can be rotated in a few directions. Handy if you're self checking or using the device to check another person. The display on the 500C is also a bit fancier - it's two color and can display a waveform graph of your pulse strength (the 500BL also displays pulse strength with a simple bar graph). The main reason I upgraded to the 500C is that the device can be set up to make an audible beep sound of your pulse. Unlike the 500BL, the 500C also has an auto off feature. Once you remove your finger from the chamber, it powers down after a few seconds (you have to manually turn off the 500BL). From the packaging and documentation of the Zacurate monitors I own, one gets the sense that this is a company that cares about the products it produces. Recommended! :)

I really like the Zacurate 500C Elite fingertip pulse oximeter. It is easy to use and gives quick readings for oxygen level and pulse rate within seconds. The display is clear and bright, so it is easy to read even in low light. The device feels lightweight but still solid and well-made. It also comes with useful features like a rotating screen and alarm, which makes it more convenient for different users. It is helpful for checking health at home, especially for sports or general monitoring. However, like most fingertip oximeters, the accuracy can be affected if your hand is cold or if you move while measuring. So it works best when you stay still and follow instructions. Overall, it is a reliable and easy-to-use device for quick health checks at home.

Works great. Accurate to my blood pressure machine. I also enjoy the casing and coloring. I fits my large fingers nicely and has a nice easy to read display.

So glad I got this pluse meter to keep check on my oxygen level. It works great and at an affordable price. This is a good one to buy.

As expected does the job intended

great tool to have on stand bye

Seldom need it, but works well

With the inability to get either a PCR or RAT test in Qld at the moment my GP advised to get an oxymeter and concentrate on blood oxygen levels. This one is fabulous. Neat, easy to use, reliable and it was delivered in three days. Very happy.

Very easy to use product
