Works great and easy to read, also great that it comes with a case to store it in.
It worked for about two days and then it started to malfunction. It couldn't read battery power even with new batteries in it. Then it take a long time to read the saturation and pulse. The battery cap keeps falling off. It looks nice and efficient but it not. Sorry.
Very pleased with this pulse ox. I bought one for myself and two for family members and all seem to be accurate, easy to use, and portable. They arrived as advertised. If I purchase another one in the future, I'm very likely to pick this vendor and product again.
seems accurate. easy to read also
