- a***p (83)- Feedback left by buyer.More than a year agoVerified purchaseOut of concern for a form of sleep apnea, I decided to monitor my resting oxygenation to see whether I need to have a sleep study. Sports watches are not that accurate so am trying this. It fits securely, comfortably and checks against y portable pulse oxymeter. App saves the results and can be downloaded for reference. Good deal

- c***o- Feedback left by buyer.Past 6 monthsVerified purchaseReview: I ordered a refurbished Wellue CheckMe O2 Max, but what I received looked and felt BRAND NEW. Seriously—it was spotless, perfectly packed, and clearly handled with care. The device works flawlessly, and it even arrived faster than expected. I’ve had my share of “refurbished” gambles on eBay, but this seller knocked it out of the park. Honest, professional, and generous—this kind of seller is rare nowadays. Highly recommended! Would absolutely buy from again. A+ all the way! Great Value.Wellue O2Ring O2 Max Pulse Oximeter for Continuous SpO2 and Heart Rate Tracking (#394365404601)
- 3***s (19)- Feedback left by buyer.Past yearVerified purchaseGreat service; great value - the O2 ring arrived well packaged and at the earlier end of the delivery range. Product was advertised as re-furbished and was priced substantially less than a new O2 ring yet it came in its original box and both the box and the O2 ring seemed brand new. The product has been working as advertised. I am very happy with the experience!Wellue O2Ring Oximeter Continuous Tracking Heart Rate Blood Oxygen Saturation (#394116446729)
