Amazing Product
This product is AMAZING. As a nurse, I cannot believe how well this pulse oximeter works and that the price is so very reasonable. It is simple to operate. The product paired with the app seamlessly once downloaded and it is extremely functional. I love that you can create profiles for multiple users. I highly recommend this product. I was concerned the pulse oximeter would fall off while sleeping, so we are using the little rubber strap to secure it to the finger when in use. It has kept the puls ox securely in place all night.

Should it be looser-fitting for bedtime? Yes, but with a little retro-fitting, it works fine…
What other reviewers said is true – it fits tight, and is definitely annoying when you go to bed.I felt like my pinkie was in a clamshell and the clam didn’t want to let go. Very uncomfortable. BUT, read on…About the Retrofit:Looking for a solution, I rolled up two very small bandaids into little “bandaid cigars” and inserted one on each side of my inserted finger (alongside my finger) which provided a slight (very slight) “opening” of the clamshell to support my finger. When I did this, it worked well for comfort, I did not feel like my finger was squeezed an a clamshell all night long, and the device still recorded my data even with the retrofit keeping it just a tiny bit less tight. The key here is to insert a little extra padding on the white edge where the “clam” closes — vs. a lot of bulk — just a hint of extra padding so your finger isn’t squeezed so tightly. If you opt to ry this, just make sure it’s still recording data (look for the blinking light). If it’s not, you’ve payed it open too far and it’s not picking up a reading.About Keeping it on all night:It fell off once during each of the 2 nights I used it (I reconnected it when I woke during the night – then it continued recording data). So far I have not used the velcro strap designed to help keep it on – haven’t found that necessary – I don’t move that much during sleep.Finger choice: My physician friends told me any finger works for reading your data, so the choice is yours. I put it on my left pinkie since I’m right-handed and it’s convenient to have a hand free during the night.Connecting & Reporting to the App:Setting up the app was super easy.Not entirely sure how to make sense of the report it spits out into the App, but the data looks clean and the graphics are pretty simple, so I’m sure I’ll figure that out.Batteries:It’s an energy eater – you need to replace the batteries (2 AAA) every 3 nights or so.I use rechargeable, so it’s no biggie.Rechargeable batteries and chargers have come down a lot in price the past decade or so, so it’s the way to go.Rechargeable batteries require special recycling, so don’t throw them in the regular trash give them to your local recycling center.So far, happy with the purchase. It’s nice to have a pulse ox that records data.

A literal life saver!
For months I was waking up with massive migraines, feelings like I hadn’t slept in weeks, fatigued and brain fog constantly. I’d talked with my doctor about setting up a sleep study but they were backlogged. Every day I felt progressively worse and worse. Then I though “I’ll just do my own sleep study, see if I really do have apnea going on”. I ordered this device and was absolutely shocked at what I saw. I knew it wasn’t good, but not this scary! I was dipping clear down to 68% oxygen saturation (65% is where your lips and fingers turn blue). I showed my Mom this first graph and she just happened to have an extra CPAP machine stored away. She got me setup and the first night was incredible! I felt like a new human! (2nd graph). This all went down 2 months before my actual sleep study which confirmed, yep, I have a pretty good case of sleep apnea. I feel like without this tool, I genuinely wouldn’t have survived!As for the device itself, it works pretty flawlessly! It’s comfortable, stays on well through the night and uploads the data to the app with ease. Part of my nightly routine now! Only thing that’s kind of a bummer is how quick it runs through AAA batteries (a set every 8 days or so). I picked up some rechargeable batteries, which I’d highly recommend. Beyond that, solid device, well worth the price! If you suspect sleep apnea (you snore, you wake up fatigued, you have brain fog, mornings are way more rough than they used to), BUY THIS!

The function and the app where fantastic. I was impressed by the quality and accuracy of the reporting. It looks like a fully professional sleep analysis. My respiratory doctor was very impressed by the report and it got me out of having to do a hospital sleep study every year.Amazing buy!

I wore this on one hand and an NHS take-home sleep study oximeter on the other (£1000 device). While the nhs did not give me the full data, the headline ODI and low SP02 point was very similar enough to feel like it can do the job.The device is easy to use and data summary very useful for showing you what is going on and talking to a GP / respiratory nurse. I also found it useful to experiment with diet and sleeping position effects on sleep breathing. The low SP02 alarm is effective and reassuring if to avoid scary 02 drops if things are difficult.The app and printout summaries are very useful. It works with normal AAA rechargeable batteries which I always prefer compared to more expensive models. I am a 3xl and find it comfortable enough to wear every night with just the clip and no strapping. Serves as a useful torch. Screen rotation is also nice feature. Price is good compared to others. It is also regularly put on offer. Review is for deal price <£40.

This is a quality product; it is well-made and its functionality is impressive. The Android app which you can install via the Play Store works fine on my Samsung Galaxy Note 20 Ultra 5G and has a well-designed, easy-to-use user interface. The device clamps on a finger like the ones nurses use in hospitals and clinics. It samples SpO2 (blood oxygen level) and pulse rate each second and can store these measurements overnight while you sleep. I simply left the device on my index finger overnight in bed. A roll of black bandage is supplied but I ended up taking it off as the device stayed on my finger all night without it. The red LED light that shines through the finger did not trouble me as it is not bright, and the display itself turns off after 90 seconds anyway. The end knuckle of my index finger was a little sore the next morning where the device had been clamped on my finger, but nothing serious.Although the device has data storage capability, it can be used as a normal pulse oximeter for spot checks as well. To look at it has the appearance of a standard pulse oximeter, albeit the quality of manufacture and materials is noticeably better than a cheap standard pulse oximeter I already have.The device uses two AAA batteries. Four batteries are supplied in the box, as well as a lanyard, a little storage bag for the device, and a user manual. The user manual explains well how to use the device, and there is an e-mail address to contact the manufacturer if you have any questions or problems. I e-mailed the manufacturer with a query and they replied quickly and were helpful.The user manual estimates that a pair of AAA batteries should last for at least three 8-hour measurement periods.It is possible to view, save and e-mail a detailed PDF report showing statistics and graphs of the blood oxygen levels and pulse rates over the measurement period you have had the device on a finger. The report is impressive and looks very professional, and I would not have a problem showing it to a doctor. In my case I was worried that my blood oxygen level was dropping too low while I slept, but the report put my mind to rest. It is also possible to save or share a CSV (comma-separated values) file which you can import into a spreadsheet if you want to examine or analyse the data yourself.The only things that I found that could be improved are: a) sometimes deleting the data stored on the device took a few attempts; b) the user manuals that can be viewed in the app could do with being zoom-able, as the text displayed on a smartphone is tiny (a printed user manual is supplied as well in any case); c) I could not find a way of deleting a user. I do not consider these significant problems, though.Overall I am very impressed with this device.
