Snuza Hero Baby Movement Monitor Review (Tips, Pros, Cons)

Disclosure: Some of our articles contain links to recommended products or services in which we may receive a commission if you make a purchase.

As parents, we are constantly worried about our babies and it will probably never stop. I’m not ashamed! I’m definitely not the only one that has checked on the baby a million times to make sure that he is sleeping, especially just after we’re home from the hospital. To help calm at least the breathing-related anxiety, there are products available that are meant to alert parents if and when their child stops breathing. Today, we’ll take a look at one of those products with our Snuza Hero baby movement monitor review!

Overall, the Snuza Hero is an affordable, reliable baby movement monitor that can give peace of mind to parents. It is incredibly portable and easy to use, but it suffers from occasional false alarms and battery changes.

In our experience, we’ve loved this device, but others may not. Let’s break down the features, pros, and cons as well as a few tips to get you started!

Who is the Snuza Hero for?

As we mentioned, the Snuza Hero (might also include the SE label) was intended to help ease the worry of parents while their baby is asleep by monitoring her breathing. It is meant to be an all-in-one solution that can be used at home or taken on the go as there are no wires or extra pieces to worry about.

Based out of South Africa, Snuza’s company vision is to provide technology that can speak for babies that are alone and unable to breathe so that their parents can take action immediately. They have only been around since 2007, but they brought the world’s first portable baby breathing monitor to market.

How much is it?

The Snuza Hero is priced on the low end of the spectrum when it comes to other baby movement monitors that range in price from around $99 up to around $250.

You’ll find it available at most retailers for around $100. If you want, check it out the latest 2019 version here (for latest reviews and to buy on Amazon). There is a new color available! All in all, we have not personally regretted our purchase one bit. In our opinion, peace of mind was worth every bit of the purchase price. I think you will agree as well.

How does the Snuza Hero work?

This device is extremely simple to use. Like, so simple you really don’t need the instructions. I’ll give them to you anyway, though!

What are the Snuza Hero Instructions?

  • Fold the front edge of your baby’s diaper over once to make it thicker.
  • Use the built-in clip to attach the Snuza Hero to the baby’s diaper so that the sensor makes contact with the belly.
  • Press the ‘on’ button on the side of the unit. It will vibrate and beep to let you know that it is on.
  • A green indicator light will flash each time the device records movement.

What is the alarm feature?

From that point, you will just let the device do its thing. Every time your baby’s belly moves from taking a breath, the device will record it and reset its internal timer. If your baby seems to have stopped moving (breathing) then the device will alert in the following ways:

  • If the abdominal movement is weak or falls to less than 8 movements per minute (extremely slow breathing) it will alert with beeping.
  • If there is NO movement at all for 15 seconds in a row (no breathing at all or not detectable) it will vibrate in an effort to rouse the baby.
  • If breathing resumes, nothing else will happen.
  • If there are three incidents of no movement for 15 seconds, it will wait 5 more seconds and then alert with beeping.

Basically, the goal of the Snuza Hero is to only alert if there is a serious problem. It’s interesting that it will first try to rouse the baby in case she is in especially deep sleep or maybe the sensor just stopped making contact with the skin. Since loud alarms can scare sleeping babies, it builds in this buffer to soften the blow.

How do you change the Snuza Hero battery?

The Snuza Hero should come with a battery pre-installed along with a few extras as well. In our particular experience, the original battery lasted for at least a couple of months of use and I think we changed it one time before we stopped using the device as our son got older.

Changing the battery in a Snuza Hero is a simple process that just involves using a tiny screwdriver to open the back cover. At that point, simple replace the old battery with a new CR2-style battery. Be sure that the battery is facing the same direction as the original or it will not work.

What are the Pros?

  • Extremely portable – drop it in the carrying case it comes with and throw it in a bag and you’ll have a portable breathing monitor wherever you go.
  • One-piece with no installation – there are no bases, wires, or control boxes to worry about when using this product. There is no setup or breakdown time.
  • Battery-powered – there is no need to worry about carrying around a charger for this device.
  • Low price – at around a hundred bucks, the Snuza Hero is pretty cheap compared to some other models in the market.
  • Rousing feature – this is one of the only devices that has a rousing feature meant to get a baby’s attention and restart breathing if they have stopped. This is pretty useful because SIDS-related deaths can occur when the baby’s own rousing reactions fail them. Just like other devices, however, it is not approved by the FDA as a medical device to prevent SIDS.

What are the Cons?

  • Battery-powered – This can be both a pro and a con, depending on your situation. Although there are no wires, you will have to change batteries. More than a few reviewers on Amazon mentioned that the batteries have to be changed with annoying frequency. Side note – The SE model uses a CR15270 battery that you can find in most stores (check the watch section). Other models use the more specialized 14250 that you won’t be able to find as easily.
  • No app connectivity – Other baby movement monitors can push alerts to a smartphone app in case you aren’t in the same room and have trouble hearing the device itself. The Snuza Hero does not.
  • False alarms – The Snuza Hero relies on device-to-skin contact and clips onto the diaper which means that when the baby moves around the sensor can move away from the baby’s belly, fall off, or otherwise cause problems. If this happens, you’ll get a false alarm. Many reviewers on Amazon reported that these false alarms happened with annoying frequency.
  • Hard to attach to a sleeping baby – Some other alarms are less intrusive than the Snuza Hero and can be slipped on pretty easily to a sleeping baby. Since you have to clip it onto the front of the diaper, it can be tricky to do so without waking baby.

Personal Testimony

We went looking for some kind of movement monitor to put on our son shortly after he was born because we had a hard time getting him to sleep outside of our bed. In the beginning, he seemed to nearly always want to breastfeed and we weren’t able to get him sleeping in his bassinet away from us. We were scared about letting him co-sleep in our bed but figured with some proper preparation and a baby breathing monitor we could keep him safe.

For us, the Snuza Hero worked really well for our purposes. It became part of our bedtime routine to bathe the baby, lotion him down, and clip the device onto his diaper before we put the pajamas on. The device worked as advertised, but we definitely got some of the false alarms noted in purchaser reviews. It was never often enough to annoy us too badly, but they were a thing we had to deal with from time to time. It seemed like in the beginning, when he wasn’t moving a lot, that the alarms were less frequent. As he got older and moved around more though we had more issues. By that point, however, we stopped using the alarm every night and eventually stopped using it altogether once we felt confident that he could move around better on his own.

The unit we received also had a working battery and, so far, we haven’t had to change it yet after several months of use. Of course, your mileage may vary!

Snuza Hero Baby Movement Monitor review summary

Overall, the Snuza Hero monitor has been a solid piece of kit for our family. It was relatively cheap and got the job done without being overly complicated. We enjoyed the fact that we could easily take it with us on trips and it has proven to be pretty durable during the past 7 months.
