TLDR; Get this one over others
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.

This is the monitor you’ve been looking for
This is the best of all worlds! We’ve been using this for 3 months with our little one and we keep talking about how much we love this monitor. With competitors like the Nanit, I convinced myself I needed WiFi. But the nanit didn’t offer a receiver, and I didn’t want to have to use my phone all the time. Not to mention their subscription or the huge price tag. When I saw they released this monitor I grabbed it as fast as I could. It was the 5th monitor I bought after sending 4 others back. The quality of the video is perfect during the day and nightmode. You can zoom up to 8x which I don’t think is necessary, but it’s fun to have the option. It has all the features of monitors on the market, AND it connects to your phone via WiFi. I love that I can look at the last 24 hours of activity and even save videos if I want to. With a WiFi monitor, I was creeped out by security horror stories. So far we’ve had zero issues with security. Ultimately, this monitor is perfect if you’re not looking for stats and a bunch of data that you don’t actually need. And if you want that, I think eufy sells a smart sock that can pair with the monitor. Can’t recommend this enough - I tell everyone about it. It’s the perfect product.

Lots of issues, don't buy this.
Updating my review here, there are quite a few more issues than I originally noticed with this camera. In fact, in my original review, I said that the camera was great, but the mounting arm was quite poor and frustrating. The company (to their credit) refunded me for the ENTIRE amount of the camera. This was almost concerning, why would you give me the entire amount back for a complaint about the mounting arm? But I think the company is moving away from this specific product and I would no longer recommend it to anyone, I'm happy I got my money back, but I'm now running into technical issues that I didn't have before. The connection is shoddy, I'm well within the 20m range, with just two (always open) doors between the camera and the monitor, and it very often has difficulty connecting or needs to buffer, this isn't very helpful when the baby starts crying but I don't see or hear it for 10-20+ seconds (or, I hear it in real life before the monitor shows it). Additionally, the monitor now often recommends (almost every time) that I switch to local connection for better streaming, but then the App doesn't work anymore. I choose 'cancel' but the prompt keeps showing up. Also, I now can no longer access the camera through the app even after turning off the monitor, because of this setting.. despite a mention of 'Smart Connect' that supposedly switches between local and wifi connection for the best performance. The Monitor itself, doesn't connect to the internet, from what I can tell, it is just tethered to the camera through bluetooth, and I think this causes a lot of the connection issues. If both pieces of hardware had wifi connections, I think we could keep a better signal. Lastly, there's a QR code sticker on the camera that you use to set it up, but be warned, if this gets ruined or lost, you have to contact support for help. There's no way to 'detect' a nearby device and connect that way (as you do with literally any other IOT device but hey). Bottom line, I'm glad they paid me back for this camera, I think it's a very poorly designed product. The Camera quality itself and monitor, independently, seem quite good (image quality, etc.), but the implementation is terrible, I will likely be throwing it in the garbage and looking for an alternative. All anyone needs in a baby monitor is a reliable and seamless connection, and this product fails in that regard, and to me it therefore fails as a product.

Excellent quality and features

Quería amar este monitor, tuve una versión anterior y funcionaba a la perfección hasta que se cayó y dejó de funcionar, decidí comprar la versión siguiente y dejó mucho que desear, falla mucho la conexión y todo el tiempo se está yendo la imagen, sin importar si está conectado o no a internet, el alcance es bastante poco y no da mucha tranquilidad que puede estar funcionando perfecto horas y luego de la nada se va la señal y se pierde el audio y/o video Se ha ido la señal varias veces en la noche sin avisar, solo no sirve el sonido y no te avisa, me he despertado escuchando el llanto (gritos) de mi bebé a través de la puerta porque el monitor dejó de funcionar. No lo recomiendo

Eufy are great products we have multiple cameras around our house and I’ve never had a problem with any definitely recommend the brand. However massively disappointed they sent me eu plugs in the box it shouldn’t be hard to work out if it’s perched in the UK to put the right plugs in the box.

Love this camera! It’s been very useful so far, picture is very clear and sound is great too, love that you can use it with the eufy sock too! The app works really well and it’s wonderful that you can see it from anywhere on your mobile device. Few things I didn’t love was the battery doesn’t last long so I just left it plugged in, the clamp it comes with isn’t great as the camera is super heavy so I ended up buying a $40 floor stand and that solved my issue. The crying detection is glitchy too. I still feel like the product is wonderful despite these few things.
