I have several extra oximeters that will not use, I bought a bunch of them for the extended families and these that leftovers. They are brand new, never used. They require 2 aaa batteries (not included). They are from a pet, smoke, and covid free home. 2 x finger pulse oximeter model: a2 - $18/each ( paid a lot more for them) U.P.U./Local/Cash only/will only reserve once we confirm a time to meet, this ad has been placed in other websites ( more pictures options) if the ad is up, then it's still available. Low ballers will be ignored If interested email or call/text me
