Yonker YK-820MINI Handheld Pulse Oximeter Probe SPO2 Blood Oxygen Sensor for Children Kids(Child)

It did the work with Yonker pulse ox which inordwred at same time

I gave this product 2 stars because it did worked for a second after i jimmied with it. Literally read for a second then back to not working

this is the worst piece of xsmms##$xlsdjks I've ever bought....They may as well just take your money and not send the damn thing..would be less frustrating.
