Babytone Baby Oxygen Monitor, Baby Sleep Monitor, Tracking Avg O2, Pulse Rate and Movement for Infant, Wearable Foot Monitor with Bluetooth and APP, for 0-36 Months Newborn's Sleep

Works great for its purpose: baby sleep monitoring with alerting if blood oxygen drops too low or heartrate is abnormal.I purchased this product because I wanted to keep an eye on and get alerted if my baby's blood oxygen levels dropped for whatever reason while he was sleeping. When my baby is sleeping, the product reliably measures blood oxygen and heart rate, and I've tested that it does alarm if blood oxygen drops too low, by holding my breath while wearing it on my finger.From my informal testing, the device will alarm if blood oxygen falls below 90%, or if the heartrate falls outside of 80-150 bpm, which actually works out just fine for my baby, as his heartrate is around 120-140 while sleeping. If the readings fall outside of those ranges, the product will emit a loud alert from the sensor itself and/or from the smartphone app (if you have it open). You can decide whether it alarms from the sensor unit, the phone app, or both. Note that you will not be able to set separate or custom thresholds for when to alarm on blood oxygen vs heartrate; you can only decide whether to turn both alarms on or both alarms off.I ended up dedicating an old Android phone to running the app, and that worked out pretty well, as the screen remains on when the app is active and the alarm is loud and will vibrate the phone. You do have to keep the app open and active on the screen to maintain the audible alarm functionality, but that seems to be a limitation imposed by Android (and presumably iOS, too).

Perfecto para un bebé y mantenerse uno tranquilo , porque monitores bien al bebé

This was a gift for my daughter and provided her with some peace of mind; however, there are also downsides to this device. Primarily, she said it would often become displaced in the night causing the alarms to be triggered, which obviously would cause her(mother not baby) to be startled awake. Needless to say, she ended up discontinuing use during the night.However, the device seemed to function accurately when it stayed in place and she would regularly monitor her baby throughout the day. (Her daughter had a problem keeping her oxygen levels up, which was the main reason she wanted a device like this.)

These work well without WiFi but otherwise they are not as accurate as name brands owett.

I got this product because I wanted to monitor my 10 month old daugther while she has a cold. The first item was delivered to the wrong place so it never showed up, so I got a replacement and it came in a dirty box with the items inside being out of the packaging. I still wanted to give it a try because I really need it, but it won't work and the only thing the screen displays is Error 4.

It’s easy to use and accurate. My son is 7 months old; he was on oxygen the first 5 months of life. When all his at home medical supplies were given back, I wanted something to spot check his oxygen. He got a cold, his lungs weren’t ready for it and this little monitor alerted us that his O2 saturations were low. I highly recommend this product and am very grateful for it.

Only way I got any sleep as a mom especially new moms I recommend for sure. Gives peace of mind

I have Drs tell us to not trust this type of home devises when we had a real concerns about our baby’s breathing. Thanks to this we determined our baby’s oxygen been low for long periods of time, when took him to ER I left this on so I can compare it with hospital device and results where very accurate. One down one up, give or take.
