O2 Vibe Sleep & Fitness Monitor - Oxygen & Heart Rate Recorder - Wearable Health & Activity Tracker

First, I have never written a product review, although I do enjoy the endless emails I receive wanting my opinion on the Ping Pong balls I purchased. Second, I am a medical engineer with 35 years of product design experience. Third, I live in Denver. I have purchased a few of the cheap finger pulse OX toys, to see if I could track my O2 during sleep and exercise. That was a big NO, they seemed to work as long as you had your finger in just the right place and a fresh set of AAA batteries in your pocket. I thought I would give the BodiMetrics monitor a try. It worked right out of the box. Good thing too, because the money they saved on the instructions, they put into the design. It was very comfortable, both the sensor and the wristband and it started working right away. I wore it to bed the first night, and I forgot it was on, except for the buzzing when my O2 dropped below 90. (you can turn that off) But there is more, there is a very professional app (IOS) that it talks to, so you can display the entire sleep cycle, it even gives you all the useful information right at the top and you can even name the recorded cycle. (like workout, Bike 700calories) One concern, there is a little band of silicone on the bottom of the sensor that keeps it closed, if it breaks, it is useless, lets see how long it will last. BUT I have to say, that is what makes the sensor so comfortable to wear for 8 hours. One last thing, since this is to be mostly used by people shown in the picture (old), the display needs to be about twice as large to see it well without glasses. (most likely designed by a much younger engineer) I can see the need to conserve power, but the display is off in sleep mode and if you are exercising with it, you really can't see it. A small price to pay for comfort and accuracy. And Last. Super good information to share with your Doctor, pulse rate alone is a very small part of the picture when it comes to how everything is working.

Good idea, does not work. I ordered this for two reasons. One, to monitor my O2 during sleep, and two, to monitor my O2 during hiking. Round 1. The display did not work one the first one I received. I called the company and left a message. Mr. Friedman, COO returned my call. He had me run through some tests and determined it was not working. I said I would just return it and get my money back. He asked if he could replace it and give it another chance. He said that all he wanted was an honest review. He said he would ship it 2 day mail. I got it 3 days later with a 3 day label. Round 2. This one worked. So I played around with it a bit. The first problem I had was getting the data to my phone. The instructions are very bad and the youtube video is almost as bad. I called Mr. Friedman and left a message. He called back later, but there were what sounded like dogs barking and kids yelling. I could not understand a word he said. I told him that and he was quite rude. It was a short phone call. I finally figured out how to get the data to my phone. It only allows you to save 3 events without using the cloud. That is also the only way to get the data to your computer. It needs a windows interface. I used it that night and it did vibrate when my O2 levels dropped below 90. The next day I tried it when I went for my walk. I put it on the activity setting and started walking. Once I got my pulse up a bit, it quit displaying the O2 levels and pulse rate. All it was recording was my steps. So, I checked that and it was off by over 20% less. Yes, I actually counted my steps. Occasionally it would display an O2 reading and pulse rate. I thought it was strange that walking up a steep 1/2 mile hill it showed my pulse at 110 and when I went down the hill it showed my pulse at 150! Since I know the data is wrong when I walk, I do not feel comfortable trusting the data at night. I really wanted this to work. It is a great idea and relatively comfortable to wear. If it worked it would do exactly what I wanted.

This device is actually amazing and I would highly recommend it for anyone who wants to monitor their SpO2 levels and heart rate. I'd give it five stars for innovation and design, but Iit does have a few drawbacks that could be easily fixed. First the pros: it is the only thing at this price point that will monitor your SpO2 and alert you when it drops below whatever setting you input (say, 85 %). Other such monitors are bigger and cost hundreds if not thousands of dollars. It records your heart rate and SpO2 all night (or all day) long and then synchs to your smartphone to give you a full read-out and record if your heart rate and Oxygen. I've attached a screen shot. I love this feature. And, as described, it does indeed vibrate to alert you or wake you if your O2 drops below a pre-set level (you set the level on your phone). Now the cons: First, the internal battery only lasts about 9 hours. If you sleep longer than that, it will run out. I think they could easily have put in a slightly larger battery. The numbers on the read-out could be slightly larger, too. But overall it is a great device. Nothing else on the market like it that I know of at this price point.

First one stopped charging after a week but they did eventually send me a replacement. Quality is lacking for the price, it's flimsy. I wore it for a week every night, and it seemed to monitor my oxygen levels fine. First 2 days, I wore the sensor on my thumb as suggested, and got low O2 ratings multiple times a night. It freaked me out but then I decided to wear it on my index finger. After that I did not have another < 90% rating. Other than that, it worked fine. It pairs up with app and downloads data to the phone quickly and easily. App doesn’t have perfect User interface but does the job of recording data fine.
