FL400 Pulse Oximeter with Neck/wrist Cord Carrying Case and Batteries Black

I purchased it back in 2017, and I’m impressed that it’s still working perfectly after all these years. I originally bought it for my mother to monitor her levels at home. To be safe, we occasionally bring it along to her doctor’s appointments to compare the results with their professional equipment, it consistently matches their readings and proves to be very accurate. It’s been a reliable health tool for our family for over 6 years.

Great product. Works as described and works well.
