My baby was a preemie so we were super reliant on watching the heart and oxygen monitors. We decided to get a Eufy and we love it!! The app is accurate, it’s easy set up and you can take it anywhere. I love how it’ll tell you when he’s moving, sleeping, and tracking the heart rate for worried mamas. It truly is amazing and helpful to prevent any problems early on. Also the battery lasted me a few days and it comes in two different sizes so it’ll grow with them. Highly suggest if you are an anxious mother to invest in one! Also doctors warned me about certain brand socks burning the babies foot but that 100% wasn’t an issue with this one from my experience. It seemed very comfy for my baby as well.

If I could give this ZERO for a review I would! The product does not work! Constantly disconnecting, it doesn’t matter how or where you place the base. The customer service is even worse! I tried emails, “live chats” which is just a robot who disconnects the “chat” when they ask you for serial numbers, proof of purchase, and your wifi information. Sucks if you got it as a gift! DO NOT BUY! DO NOT ACCEPT IT AS A GIFT! Have them return it and just get the owlet one! You can’t see the database that shows you how they did over night, you can’t see anything while the baby is wearing it to verify it’s working and that everything is fine.

On top of that they ask you for the same information you’ve given multiple times! I’ve never dealt with a company or customer service so awful! I’m am irate with this entire experience and the product! DON’T WASTE YOUR TIME OR MONEY!

We originally bought a secondhand Owlet monitor from someone. The older monitor app wasn't compatible with our phones, so we needed to find something else. Owlet monitors were out of our price range at the time, so we looked for more affordable options. We came across the Eufy sock monitors. I do not have an Owlet to compare it to, but I cannot say enough about this monitor. It is easy to set up and easy to use. Thankfully we never had an emergency happen, but our baby somehow got the sock way off from where it was supposed to be while she was sleeping. The dock automatically alerted us and so did the Eufy app. It helps track heart rate, blood oxygen levels, and sleep time. Again, I have nothing else to compare it to, but I would definitely buy Eufy again if need be.

Loved it until . . .
20 February 2024

I was gifted the eufy baby foot monitor with camera. I 100% loved it up until recently. All Wifi cameras can be hacked. Ours has been hacked multiple times. We’ve changed the passwords and wifi but still have had this issue. We had the camera light turn on or the camera rotate while only my husband and I are the users and both of us were asleep. It’s scary. Definitely recommend looking into a camera that does not need to connect with wifi.Beyond that if you do purchase just be careful. I loved that the foot monitor gives us all the stats and helps keep track of sleeping patterns, specially as a new mom. The camera is amazing quality and until being hacked had no issues.

PIECE OF MIND
28 December 2023

Our baby has been a light sleeper since day one and we ended up putting her in her room in her crib at 3 weeks because of us getting in and out of bed during the night woke her up. This stays running on our phone at night with the sock base on the night stand and I am able to check it through the night. It updates and gives real time heart rate and oxygen levels. It’s pretty accurate except when she is in the swing asleep it will say she’s awake because of the movement, but it tracks sleep and wake times accurately other than that. We went to put a bigger size sock on her too early and it wasn’t fitting right so it went off in the middle of the night to “check the baby” when it read her heart rate at ~66. It is loud and will wake you up even if you are sleep ... MoreOur baby has been a light sleeper since day one and we ended up putting her in her room in her crib at 3 weeks because of us getting in and out of bed during the night woke her up.

It is loud and will wake you up even if you are sleep deprived and resting like a rock.Well worth the money, we have used it every night with the eufy security camera and charge it during the day. Would buy again 100%.

Sleep with peace of mind!
6 February 2024

After our son went unresponsive on us at 2am I knew I needed something! We have twins and it was easy to set up both profiles and they are amazing!!!! Keeps my babies heart rate and oxygen level me personally thats all I care about!!! My daughters heart rate dropped one night and it alerted me immediately!Sometimes it will say my child is calm when he/she might be moving around or it will say wiggly when they are not, I think its just the dely to the base! I did not buy them to track my twins sleep. I bought them so I know my babies were breathing all night long. I highly recommend this product!!!!

[Rewarded Review] Must have for parents with newborns
19 April 2024

I was able to test this product out through Influenster for my honest opinion! This product is designed to track the baby's vital information such as heart rate, oxygen levels, and sleep patterns. It connects to a smartphone app that allows parents to monitor their baby's well-being in real-time and receive notifications if any abnormalities are detected.This product gives parents an ease of mind when they lay their baby down to sleep knowing they will be notified of any abnormalities while baby sleeps. Making this a must have for all households with newborn babies

[Rewarded Review] Neat product
22 April 2024

This is a really neat baby monitor. It can track baby's sleep patterns and monitor heart rate. The setup instructions are easy to follow. We have had some issues with notifications, which may be due to our Wi-Fi or trouble with distance in the house (sock too far from the base). I wanted to have the base in our room, and sock would be in the baby's room. But the distance may be too far. I do wish that it could monitor oxygen and give notifications for that as well. Overall, it is an affordable option for monitoring.

SIDS is every parent's worst fear. Babies are so precious we worked so hard to get them into this world and all you want to do is protect them unfortunately some stuff is not in our hands but with the EUFY S320 smart sock you have peace of mind and have a better knight sleep knowing that you'll get signals if you need them instead of hovering all night over their crib. Also because of this fear I had a hard time transitioning my baby to his own nursery. And if you wait too long this task gets very difficult and your poor baby gets so offended and scared because they're not used to sleeping in their own room. But if you start early and stick with it you and your baby will have a better sleep and you'll be a much happier and productive mom.I love the fact that the ... MoreSIDS is every parent's worst fear.

But if you start early and stick with it you and your baby will have a better sleep and you'll be a much happier and productive mom.I love the fact that the smart sock has a sleep analysis and repeat so if I do have some concerns I can share it with our pediatrician. The sock is comfortable baby doesn't really feel like because it's so soft and breathable. The best part is it's also washable.Another amazing feature is that you can view the status of your baby's sleep wherever you are so you're not afraid to bring a babysitter and go out and feel human. You also get instant notification on your phone.It also has a real-time led indicator to let you know that when you see the green glows light at the Led base station all is good.Also you get notification when your baby is not comfortable the LED light turns.It also has an accurate reading it uses a fresnel lens to ensure it gets the accurate.I love the fact that it's chargeable and you don't go through a ton of batteries.Box comes with the base, the sock, sensor, power adapter, power cable. And A Quick start guide.The instructions are very clear and it's user friendly.I think this can also make a very sweet gift to someone you're close to especially close relatives. So your family feels the love and how much you care about them.I wish this product was out there many years ago it would have saved a lot of baby's lives.But it's here now and I definitely recommend it to everyone.I'm so grateful to influencer for sending me the S320 Smart socket by Eufy For free and return for an honest review.

[Rewarded Review] Such a good thing to have!
19 April 2024

Received this eufy Baby Smart Sock from Influenster for free! I absolutely love this sock. It seems to be comfortable on my baby’s foot. It’s not too thick at all. Seems like it works amazing. I love how it shows the oxygen and heart rate all in one app. I love how this keeps track for their sleep during the day and night and sends you notifications about new sleep patterns. The battery life isn’t the best. It last a good 24 hours tops which makes it inconvenient at times to charge it when it baby doesn’t want their foot messed with when putting it back on even though it is very easy to put on my baby seems to hate his feet messed with but once it is on it’s fine!
