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

there were instructions for easy use. Batteries were included.

Great product!

Bought for my dad who has pulminary fibrosis. He loves it for measuring his oxygen.

My doctor was worried I wasnt getting enough oxygen while I was sick (not covid). I have really bad asthma when Im sick. This was the best way to tell if I needed to go to the ER or not. When it dropped to 85 I really needed medical help. I could still breathe but I wasnt getting enough oxygen. Thankful to have purchased this or else I wouldnt have known.

That it works well

This is exactly what I needed. It is fast & accurate, easy to use.

As described did come with a soft shell style cover

Works as advertised.

I liked everything about the item.

This is great to have around, especially if you have asthma. Product is exactly as described and pictured. Its easy to use, takes 2 AAA batteries which are included. Also comes with a lanyard.
