    • Great affordable option!
The sense-u saved my sanity at night. As a first time mom, I was checking my babies breathing constantly. The sock monitors their blood oxygen and heart rate, and even tracks their sleep. It lets you adjust the levels in which it will alert you to check on baby which I find really helpful. It has good battery life and lasts all night and through my baby’s morning nap. It says connected very well and is easy to navigate through the app. I haven’t had any issues with the functionality of the sock either! I highly recommended as a affordable option! ... show more

    • Great sock, Low price!
I love this monitor so far. It’s very easy to set up and gives us peace of mind while our baby is sleeping. It is very accurate (we tried it on ourselves lol). It’s a good fit for a cheaper price than the Owlet. The connection is good and the sensor doesn’t bother the baby at all, it seems comfortable. I love the different functions it has in the app and how you can set them yourself as well. 5/5 for us! ... show more

    • LOVE THIS AS A FTM W/ PPA!
I love this sock. I have noticed that the sleep stats are not very accurate, but it has given me (a first time mom with terrible PPA) an immense amount of peace of mind. It was easy to set up and its easy to just put on her foot every night and no false alarms. I would absolutely recommend this to anyone that is struggling after having their baby. ... show more

    • Buyer beware - Not as advertised.
This product is absolutely terrible. Has a range of about 5 feet if it fully functions at all. The app is constantly disconnecting or reconnecting. When connected it will often only show the blood oxygen level and not the HR. The data was non existent, never giving us a true readout of how the baby actually slept, often telling us she slept 20 minutes or simply showing no data. I believe the HR and Blood Oxygen when displayed were often wrong also. We bought this to ease my wife's mind without needing to look into the crib or shine a light on the baby while sleeping to check her breathing and it's not helped at all. We thought we might be able to be in the other room and use our camera in addition to this device to check on her and that was never once possible. Had to be in the same room which defeats the purpose. Also we set up notifications and were never once alerted. To return to the USA costs and additional 140usd so I am stuck with the product. Buyer beware. ... show more

    • Disappointed 😢

Disappointed. We have had it for a month and it was good. I noticed it wouldn’t alert me when her heart rate would drop even though I have all the settings turned on for that and my phone is ready to receive those.( do not disturb isn’t on and the app notifications are on.) but then the other day the app told me it needed to update and after the update we use the socket at night and it won’t stop saying evaluating or calculating, and and then says to adjust the fit, which I adjusted the fit probably 10 times and it was never good enough. Even when it would monitor, it would cut in an out so I wouldn’t know if there was a problem anyway. She would be holding completely still at night and it would still say that it couldn’t find anything so we haven’t been able to use it since. I reached out to the company for some help but definitely gonna switch over to the owlet sock if they cannot fix the issue. Unfortunately there’s no option to return it. I’m very disappointed, considering the amount of money I paid for this. ... show more

    • Gives me a sense of mind
After having a baby in the nicu for 3 months, coming home i wanted something to give me a peace of mind. This sock did just that. It’s comparable to the other brand name one but at a fraction of the cost. The battery lasts all night and once charging the app will inform you when the charge is complete. I do wish they had a 3rd size. One in the middle of the two because the small sock is almost too small but the bigger sock is way too big. But overall the sock is easy to work, the app is easy to use and easy to connect to WiFi which is all nice. Overall I would recommend this product, especially for the price compared to the other one. They both do the same thing, but this Sense-U sock won’t give you false readings. ... show more

    • Accuracy, Battery, and Fit Issues
Not very accurate, but it works most of the time. My main issue is that sometimes the heart rate is actually half of what his heart rate really is. Every so often (ten minutes, once per day) the app will show heart rate at like 65 or 80, and I check his heart rate manually and it is nearly exactly twice as much. The battery life is very short. It does need to be charged every single day if you plan on using it throughout the night. There are some issues with the fit, but for me I did not have many issues with the connectivity. It stayed connected all the time. The fit indicator almost always shows a poor connection because of how it fits on his foot. No matter how I adjust it, it will show a poor connection. I could have purchased a used owlet for the same cost and it would have worked better. Not sure this was really worth the money. ... show more
