Checkme™ O2 Max Wrist Oxygen Monitor

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.

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.

Glad that I bought the product. It gave me information about my quality of sleep and what I should do to get better sleep. Easy to use and reasonably comfortable to wear at sleep.

Suggestion to company: Enlarge the scale for the Motion chart as it wouldn't spike even when I am getting to and from the washroom.

It's a great device that my wife wears 24/7 she wears to go to sleep it vibrants when her oxygen levels drop so can regulate her oxygen day and night she's on oxygen 24/7 thank God for this wonderful device to make it easier for me since I'm my wife's care taker .

The wristband is my only concern. If you have arthritis in your finger's, it is hard to fasten the band.

After my wife had departed and then come back to her body, she was put on oxygen again. Too much oxygen is what killed her in the first place, so I needed a device where I could monitor her daily status so I could adjust the flow meater to keep her from passing again. This device has an alert for low level of O2, but it should also have one for a high level of O2. At any rate I use the daily report so I can see her average throughout each night and I use the alarm if she goes below 87. I have been able to adjust the flow meaters on the two machines I have in the house and now have them each dialed in so she will average 93. The Checkme device has allowed me to accomplish that task.

Much more comfortable for long term wear than the O2 ring

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 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
