Been using this for our 7.5 month old since we brought him home. I like the peace of mind it gives us. It's not 100% accurate but it's pretty close (in terms of determining his sleep, heart rate and blood oxygen level). After daily use for 7.5 months it's still going strong. Maybe once in a blue moon it disconnects but never for more than a few minutes.

After owlet discontinued the support for older socks, we were faced with a decision I wasn't expecting. After some research we decided to go with eufy, and I'm SO glad we did. We have been using this every night for about a month now, and so here's the in-depth review I wished I could have had at the time I was looking. The sock design is so much better than other ones out there. I have no struggles putting it on since the sensor goes right on the top of the foot. Super simple. I also personally have not had any issues with the sock part being super worn or falling apart either, though she only wears it at night. If it does happen to come off for any reason, the base calmly tells me and there's a little image that lights up. It is so much better than the blaring music of previous products I've had. I personally rely on the base rather than phone notifications and I've had no issues. You can turn off the notifications it does if you want to keep it in baby's room (since it does charge it). It is wonderful for peace of mind, but it does so much more than that. It tells me how good my baby is sleeping, when and how often she woke up, her heart rate, her oxygen, if she's moving around, and how much sleep she got overall. I have my daughter in a mini crib a few feet away and this wonderful base has an image that lights up when she's wiggling, and will stop when she stops. It has helped me not get up every 5 seconds to check on her when I hear noises, making my sleep so much better. I have not had any issues like other people have reported regarding the oxygen sensing. It has never been suspiciously low. The oxygen sensing is in BETA testing so it will NOT notify you if something weird happens on the oxygen front, but you can always look at it in the app. It will notify you of a drastic heart rate change though. I would suggest going into the app settings and changing the heart rate notification parameters a bit so you get an earlier notification if something starts going strange. I love the app. It is simple and straight to the point. You can also invite other people (dad) to have access to see what's going on and be notified as well. The only issue I've had is the sock not charging from putting it on the base a tiiiiny but off. It will make a noise when it starts charging so make sure you listen for it. The battery life is a little over 24 hours, so I have used it on low battery a second night and the base will tell me calmly when it's about to die. For the price, I am so impressed. I would get this over other monitoring systems out there, especially if you can use HSA or FSA funds. Love it so much. So thankful.

I have been using this for 6 months now and it serves its purpose forsure, baby had fluid around his heart so having this was critical for peace of mind. I had 5 alarms in 6 months and I’m very positive it was just me not having the straps tight enough. All these people with their one star reviews saying the alarm sucks and you can’t hear it, that’s a lie it is quite loud. There are also people saying that it stops charging… unfortunately probably just got a bad device. Then there are people saying the sock part comes apart… well don’t wash and dry it the way you have been? Maybe wash on a dental cycle and hang dry lol?

BUYER BEWARE. I had high hopes for the Eufy Smart Sock. My baby is a NICU grad with a heart condition, so I thought this would help me feel a little more at ease, especially at night. Instead, it completely stressed me out. So many sleepless nights and doctors visits were caused by this garbage. The sock kept showing dangerously low oxygen levels, and of course I panicked. I brought the readings to our pediatrician, who took it seriously and sent us home with a hospital-grade monitor to double check. That monitor showed that my baby’s oxygen was totally fine the whole time even when the Eufy sock was freaking out. I can’t tell you how scary it is to think your baby isn’t getting enough oxygen, especially when they already have a heart condition. We needed something reliable, and this just wasn’t it. I wanted peace of mind. What I got was sleepless nights and unnecessary worry. Definitely not worth it for us, such a waste of money! Customer support was not helpful either.
