Our Verdict
The Sense-U Smart Baby Sock 2 is a curious middle-of-the-road monitor that could meet your needs, but it's really expensive and may be more monitor than you need for peace of mind. While we love the video quality, and our research shows it is one of the most reliable for vital tracking and alerting, with a loud alarm you can't miss, it is hard to set up and feels mostly unnecessary. This monitor requires Bluetooth and WiFi. You have to download an app and set up an account. Everything needs to be paired up, and missing any step will require you to start over. Tracking vitals on a healthy baby can also lead to anxiety for many parents, as too much information can be overwhelming. And since it isn't a medical device, it isn't a good pick for children who need monitoring prescribed by a doctor. The single year of the vitals tracking also means that for most of its lifespan, all you get is a WiFi video monitor with great video but no sound activation. So if it won't make you anxious to get all the details, and you don't mind a wearable, we can see the appeal, and it works fine, but we think there are better movement monitors that can help ease your worries without all this fuss.

Our Analysis and Test Results

The Sense-U does some things right that make it potentially appealing for some parents. The video quality is exceptional, the app is easy to use, and it monitors more things than average, including heart rate, blood oxygen, movement, video, sound, and even room temperature. We think the sound quality is better than average, and WiFi connectivity means it could work for homes where dedicated monitors struggle.
The reliability seems good, and we didn't get any false alerts, unlike with some competitors. Online reviews also mostly say kind things about the reliability, and given how people love to share when products are bad, we think this is a good sign.

We also like the alert functionality, even if it has a bit of a learning curve to remember what all the colors on the sock and base station mean. The alert volume is loud, and it has heart rate sensitivity settings. You can change the volume and sound used for notifications, which is nice. The phone will even vibrate in case it is in your pocket and the sound is muffled. The alarm at the sock and on our phone was loud and high-pitched, demanding attention, and we think that is what parents need when sleeping. We think the alarm is more useful than the alerts.

Dislikes
Where the Sense-U falters somewhat is with ease of use and setup of the monitor. We had difficulty following the instructions and had to start over after accidentally pairing only the sock with the base station, and leaving the camera out altogether. We think instructions could be clearer and suspect we aren't the first ones to struggle.
It also won't work on public WiFi, and while this is common for the monitors that track vitals, it means it isn't a travel companion, and it won't even be easy to take it to grandma's house, as everything will need to be connected to her WiFi, which is time-consuming.

This monitor is also expensive, one of the most expensive list prices in the group. Given the shorter lifespan of the vitals tracking, for most of your monitoring years, you can't use the components that make it so spendy. Whether this is worth it depends on your goals and budget. At least this camera has a remote control and almost 360 degrees of potential viewing, with some of the best video quality we've seen.
The sock has one of the highest EMF emissions (1.28 V/m), which is a bummer since it rests on the baby's skin. It is almost twice that of the leading sock and exceeds those of other wearable competitors.

Should You Buy the Sense-U?
Um. Maybe. This one is a toughie; we kind of like the Sense-U as a video monitor, but not as much for tracking vitals. It has great video quality, an easy-to-use app without the constant push for a subscription, and loud, crisp sound. It is also pretty reliable for tracking compared to most of the competition, but the setup is harder, and remembering to put a sock on before your baby falls asleep is more challenging than you think it will be before you have a baby. It's very easy to forget. It also lacks sound activation, so we could hear something from the monitor all the time, even if it was just quiet white noise. The real bummer here is that it is expensive, because you are paying extra for the tracking. But the tracking has a lifespan of only about a year. That is one expensive year. However, in fairness, when the year is done, you do have a remotely controlled camera with exceptional video quality, which is nothing. This monitor is probably best for those with high anxiety that will be quelled with more knowledge, which isn't everyone.
What Other Movement Monitor Should You Consider?
If you want to track all the vitals, the Owlet Dream Duo Monitoring System (Gen 3) is a tried-and-true monitor that parents love. It is almost as reliable as the Sense-U, has a lower list price, and is easier to set up and use. However, the camera is stationary, so once the vital-tracking portion of the monitoring is complete, your video monitoring is limited. If all you want is an alert if your little one stops moving in a way that indicates consistent breathing, we think it is better to buy your favorite video monitor and pair it with the diaper clip on Snuza Hero SE. This wearable vibrates to rouse a baby when it senses a change in breathing and makes an audible alert if the baby doesn't move in response to the vibration.
