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

The product works well, does vibrate which gives helps partially wakes my Dad which helps his O2 levels to improve. Setting the vibration to highest level and the threshold from 85% to 87% his O2 levels increased despite COVID. He is taking medicine now to fight the infection. I was told it is better to wake him than let him sleep with low O2 levels. This device seems to stimulate him enough that he seems to wake enough to breathe better. I think it is worth it. Only thing I swished it would do is notify me by the application. Know how t doesn’t work that way but I am 99% satisfied. Better than I expected!

Very easy to use, fairly comfortable to wear overnight, and seems to be very accurate. I had a previous one that wasn't working right after about a year, so I was glad I had bought the extra warranty and they replaced it with no problems. This one has a thicker band of rubber/plastic around the finger so it's not quite as comfortable as the first one, but I'm assuming the thinner ones may have been wearing out sooner so they made them more substantial. App is very easy to use and really gives you a lot of info about your sleep and breathing, including your pulse rate and how much you move during the night.

Lookee has great products. I bought their fingertip monitor a month ago. It works great to monitor my health condition in a easy way. Benefit from it, I feel I need a bit more help, so I bought their ring. This one can monitor and record the oxygen saturation and heart rate for the whole night. I had been wondering why I am tired even right after I have a whole night sleep. This ring monitor gives me answers. My oxygen level drops from time to time during my sleeping. The function I really like is it vibrates when my oxygen level drops, so I can change my sleep position and get better breathing . Really likes it and highly recommend.

This is a good device pretty accurate and it's my second one so I'm working off of two of them so I have knowledge about my heart Etc throughout the whole day

I bought a Lookie two weeks ago to chart my terrible sleep pattern. My oxygen drops very low many times through the night. I was concerned that the device maybe inaccurate. IT ISN'T!!! I recommended the Lookie to a neighbor who is using CPAP and he bought a Lookie. We swapped last night to double check the results and accuracy of the devices and can say that they are spot on. Would highly recommend this device. BTW, I'm going to the Sleep Doctor this afternoon before they find me dead in the bed!!!
