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

Its simplicity is a plus. Its accuracy is a minus. The Blood oxygen reading is consistently one or two percent under. Pulse rate is scattered all over the scale.

Liked the design. I use it to measure my oxygen content.

Use in the office and seems good

Good price and product!

Saved my life

Easy to read and understand display for oxygen and heart rate

Works great

Use it several times daily. Looks good, easy to read, and compares in accuracy to that used in my dr’s office. I’m very happy with it.
