Hypoxic Reading, Inaccurate. BUYER BEWARE
Positive: The micro-USB recharging feature is great. I work internationally in remote hospitals where AAA batteries are expensive, poor quality, and hard to find. Anything that is rechargeable is great in these hospitals.<br /><br />Negative: The accuracy was way off and fluctuated wildly from the 70's to the 90's. I charged the unit again and tried it on myself and also with several of the anesthesia machine pulse oximeters. This pulse oximeter was way off and therefore totally useless. Since I have been overseas for the past few months, I have missed the return date.<br /><br />BUYER BEWARE: You would be much better off buying a AAA battery unit that has high ratings rather than this one. If you do buy this one, charge it and check it as soon as it arrives. If it is not accurate, then send it back for a refund.
