LOOKEE Ring-Pro Wearable Oxygen Monitor with Vibration Reminder for Low O2 - Continuous Pulse Oximeter -Rechargeable Blood Oxygen Saturation Tracker for SpO2 & PR - Free APP & PC Reports

This is a lifesaving product that provides you with great information about daily/nightly oxygen utilization. It appears to be very consistently accurate and correlates exactly with hospital oxygen monitoring devices. I find that the device can be worn on the thumb or the pointer finger with very similar and consistent reading. The battery life appears to be 5 to 7 days, depending on how much daily/nightly usage. I've had to buy the oxygen monitor device 4 times now over a 10 year time period. I needed to replace one because my dog ate it, once because I lost it, and only once because the product failed. My only recommendation that I would give, would be that there should be some kind of customer loyalty incentive if customers need to replace a product or if consdering purchases of other Lookee products.

The item works great definitely let's u know when o2 levels get low at sleep.

In a nutshell, this device didn't work for me, and I was told I needed to sleep more like a medically-standard person.... I have 4 other similar devices, which I use at night to monitor my SpO2 levels due to obstructive sleep apnea. The other ones are older, or have started falling apart, so I bought this to replace them. So I am _quite familiar with how these products are supposed to work! And this is the first one that made me feel unsafe. The first issue is that it can be wildly inaccurate! At night I was getting alerts that my SpO2 level had dropped into the low 80s, waking me up. I was so concerned I wore one of my older devices, and the next time it happened, wouldn't you know it but the older device showed a more normal level in the mid-to-upper 90s. I decided to wear both during the daytime, and the next day while talking with my wife after lunch, _this device again went off claiming my level was in the low 80 percentile, but the older device again showed a normal level. I immediately tested with a finger-tip device, and it too reported I had a normal level. I wasn't filled with confidence. But the most concerning thing is that this device--unlike any of the previous I've owned--SHUTS ITSELF OFF after 10 hours! That's right, if you wear it for more than 10 hours, it just... turns itself off. According to their customer support, this is by design and cannot be changed. I discovered this because I couldn't figure out why it was always OFF when I woke in the morning. I then had a lengthy email conversation with Lookee support. Here's the problem: I like to put on the device at bedtime, then I typically read for maybe 90 minutes before falling asleep. I'm retired, and I often have insomnia, so my sleep patterns are not regular. I sometimes get out of bed multiple times a night. Sleep is often ellusive. So it is quite easy for me to climb into bed around 9pm, and crawl out of bed sometime after 7am. My math skills are still pretty solid, and I know this can potentially add-up to more than 10 hours. Luckily, my sleep apnea never "kicked in" during that period after my allotted 10 hours were up, because I could have simply stopped breathing... but this handy device that _should have woken me had already turned itself off. To be clear, NONE of the other 4 devices shuts itself off after 10 hours... and yet, every one does indeed have a "10 hour data limit per session." The other 4 devices, each by different brands, either purge data older than 10 hours or (in one case) restarts itself, clearing the slate. This is the only device that simply shuts off! Here is a direct quote from Lookee customer service. (Honestly, I feel like the product engineers designed a device based on a written specification, but unfortunately had zero idea _why they were creating this product, or who it was for.) > "Yes the device is designed to turn off at 10 hours recording. Technically nobody sleeps more than this hours. Also this is designed in way that follows the medical standard for 10 hours recording. It is also designed to store 4 recordings x 10 hours each. Unfortunately we can't change this design of the device." There you have it: This device was designed from the start to be worn only by people with perfect sleep. If that's _you, then this device might work (assuming you are okay with wildly off-kilter readings compared to similar devices). If, however, you ever sleep longer than the medically-standard duration, then you should reconsider. No sense suffering in your sleep because this thing has shut itself off and can't alert you that you've stopped breathing! Buy a different solution. I did.

I love the product and use it daily track my nightly sleep interruptions. i had a problem with my device and customer service sent me a replacement. they were very user friendly.

It took me awhile to figure out what finger to use and the best spot to attach it to. In result, the most accurate reading I get is when I attach it to the tip of my middle finger or thumb. Overall, it is more comfortable fit for me for the overnight wear when I use my middle finger with device taped for extra security so it doesn't come off when I move in my sleep. I find this device more ACCURATE than some other brands that I have tried, battery life is plenty, it FITS GREAT for overnight wear with some taping, the ALARM function is simply AWESOME and the main reason I bought it in the first place (I had afib event w. a trip to the hosp recently due to hypoxemia... now I am reminded to breath at night now and then). Personally, I am going with the extended 3y warranty as some people complained about device quality, which probably makes sense if it is used daily.

I ordered this to track and alert me when o2 sats dropped below level. Work the first two nights then it turned off due to placement of button and fingers when sleeping the next two. Does no good if it keeps turning off. Plus readings were not same as on other two comparison oximeter. Read much lower (5 or more percent)

I previously bought one of these 5 years ago and it worked well. This one disappointed me. It would turn itself off during the night, seemingly at random. It is also top heavy and awkward when you have small fingers. I also wore it with another device that I knew to be accurate enough that a doctor used it during an appointment instead of their own pulse oximeter. The Lookee one varied enough from the old one to make me prefer to use the old one.

Extraordinario producto . Desde que lo uso duermo con mucha tranquilidad sabiendo que en caso de que la oxigenación disminuya me va a despertar. Lo recomiendo ampliamente.
