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

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.

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.

When I got this thing it immediately evokes feelings of consumerist exhaustion, like "great... what cheaply made overpriced Chinese garbage did I waste my money on now..." When I connected the device to my phone it also imported data that had already existed from someone else months before I bought it. After using it for for two nights, there was a glimmer of hope like maybe this thing might actually work. Nope! After the third night it completely fails to connect with my phone. I cannot see the data anymore. What a travesty this consumerist world has become.

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!

Small & stays on your finger. I am a very restless sleeper & it has never fallen off. Pretty accurate. When compared with my regular pulse oximeter, it was only 1-2 points off if at all. It has an adjustable vibration tone that has never failed me & best part, you download an app to your phone & it saves the dats to show your doctor. Love this little thing!!
