Checkme™ O2 Max Wrist Oxygen Monitor

Tested with other oximeter, values are OK (aproofed by FDA)
Vibration and Sound test for high or low value of oxygen (only low) and puls, OK.
Great battery time. Work to gether with smart phone. High price but unique functionality.

This little monitor does the trick. It is not that intrusive so it doesn't get in the way of my arm moving at night, but the sensor also stays put (been using it for about a week now and haven't had it come off). The software for the smartphone calculates numbers like the amount of time the saturation is >95 and the number of drops 4% or greater during the measured period. With the software for the computer, you can save this in report AND data exports to allow you to analyze to your heart's content.

Pricey home use medical device! It appears the FDA concluded that this medical device is a safe and effective product as a legally marketed device. Unlike other oximeters, it is unclear why the product or software does not document or record the perfusion index (PI)—a simple explanation may provide clarity. Concerned that one area of the rubber thumb band wrap may not be durable. Must be very careful taking thumb wrap on and off. The area of concern appears thin; may be weaken and break after minimum usage. Then the user must purchase a replacement cable for an already pricey product. The medical device performs as advertised.

I have bought and owned at least 4 different spo2 monitors such as checkme doctor, checkme max, checkme be4 max, i own all and have tested them all and they all matched readings from 1 hand using at same time on different fingers

and can say there accurate i got my 1st 1 in 2019 and then bought a family member the new max model in may2021 due to there ill health and due operations on there lungs and a weak heart

The max model has spo2 monitor plus a pulse rate monitor which both have an alarm system when they drop below a certain level then it beeps and vibrates

Support are very helpful with replacements when it comes to replacement charge/data cables or of finger sensors am a restless sleeper and due this sensors have malfunctioned and wellue have kindly replaced sensors as there warranty and guarantee is for a full year from purchase and there fast to reply within 24 hours so am very happy with there support system

Appareil très intéressant voire indispensable si on est sujet à des apnées du sommeil. On oublie facilement le port pendant la nuit. La seule difficulté c'est de fermer la boucle du bracelet. Le tracé des mouvements pourrait être plus marqué. Sinon il vaut mieux être en bonne santé pour pouvoir se passer d'un tel appareil.
Dernier élément : il est très bien emballé et la finition est parfaite !

I brought this item and fell in love , why because is very light and you can see the oxygen informacion in his own screen or your phone for bluetooth.
But the best here is the service people was very polite and kindly with me.
Thanks you.

I am so glad I invested in the wrist monitor. I have been able to easily monitor my oxygen levels and really appreciate the alarm to help me not drop to low. I have set my threshold higher to keep me in a good range before problems happen. Checkme is comfortable to wear and I am impressed with the battery life of my monitor. I didn't expect the battery to keep a charge all day long but it does! Couldn't be happier and am so glad Wellue will stand behind the customer if the monitor stops working.. Thank you so much Wellue

I bought This product 10 days ago it does not allow me to move more than 20' away from the monitor and still pick it up on my phone it also is now telling me finger out periodically when it's not

The technology works very well, no complaints. I have an issue with the wrist band. It’s very hard to put on with arthritis, and I need help putting it on at night. I did contact support to see if there was an alternative wristband but unfortunately there is not. Besides this, I do highly recommend the Checkme™ O2 Max Wrist Oxygen Monitor.

Just received my monitor in the mail after being diagnosed with sarcoidosis. So far the readings are matching up with my personal 02 monitors. I will test for a week and come back to leave an update on what it's like to sleep with the monitor on and how the data syncs up to the app.
