It works very fast with clear reading. Great for asthma sufferers needing to know their oxygen level.
Came as described and works well.
My wife worked in the nursing for years and said it seems like it’s of good quality
Im very pleased with my oximeter. Its small, lightweight, and comes with a lanyard and batteries. Its accurate and quick. I work a lot in the field so this being so small is very convenient. Ive monitored for a week to report to my doctor.

I got this because my dad is coming home from Rehabilitation and I know I'll be needed to keep a close eye on him. So far I have tried this on myself, my husband, and almost 5 year old. It gets a reading pretty fast, it seems accurate I have not gotten any odd readings. Nice lil storage case that came with it.
