Even though it’s quite new on the market, Spectra is already one of the leading breast pump companies. They offer quality, innovative models, providing moms with devices that look and work just as advertised. The S2 is their newest model and one that’s already quite popular – for a good reason, we have to say.

It’s a silent, hospital-grade pump that comes with a ton of features and sports one of the best designs we’ve seen so far. It certainly deserves a more in-depth look – let’s do it together, shall we?

Features of Spectra Baby USA S2 Breast Pump

  • Ease of use

Fortunately for all worried moms, this model has been designed with comfort in mind. It’s made especially for women who often have to travel from home to work and don’t have enough time for the proper breastfeeding. Powerful and effective, it’s loaded with features and should meet all of your breast-pumping needs effortlessly – since it successfully incorporates all these innovative features, all moms will be able to use it without inhibitions.

Since it has been dubbed as a hospital-grade model, the Spectra S2 is a very strong and efficient device. It sports the maximum suction strength of 300 mmHg and can be used both as single and double pump. This can come in very handy in some situations and is a feature that certainly deserves some special praise.

Adjusting the suction is very easy here, whether you decide to use the pump in the expression or the let-down mode. The thing that makes it so easy is the presence of the digital controls – and that’s something we’d like to see on all other electric models. We were also quite pleased to find the timer and the nightlight, which has two separate brightness settings.

  • Efficiency

As you already know, time is a crucial factor for every loving mother. With this model, every mom can be assured that no time will be wasted, as S2 is one of the most efficient electric models on the market. And the thing that makes it so efficient is the presence of the already mentioned let-down and expression modes – they make things speedy and convenient.
A mom can set the pumping program that feels most comfortable to her own body, with speed and rhythm that won’t make her feel stressed or painful. The working cycle of S2 starts with the so-called “massage mode,” which is there to stimulate the woman’s let-down reflexes and start the milk flowing. It is short and shallow, and a great way to begin the pumping session.

The expression mode, on the other hand, mimics the baby’s behavior with a prolonged and deep suction process. This mode extracts most of your milk and works flawlessly.

  • Portability

Those moms that travel a lot will be pleased to find out that this pump is very portable, as it comes together with a convenient tote. Another thing that makes it easy to transport is that the model is very lightweight – one can easily carry the S2 in the handbag.

But, unfortunately, there’s one thing hampers its portability, and that’s the fact that this device cannot be run on batteries, or on any other alternative power source. This means that you’ll always have to hunt for the power outlets, which is something we hope to see fixed in the next revision.

  • Comfort

The Spectra S2 provides a customizable pumping experience, which makes it easy to set the speed and the rhythm that feel the most comfortable to you. The fact that it mimics the baby’s behavior during breastfeeding makes every session very gentle, while the let-down mode can provide you with a very relaxing start of the session and efficiently make the milk start flowing.

The ability to modify the speed reduces the painful tugging on the nipples, while the presence of the nightlights allows one to pump the milk even in total darkness. The display and the control buttons, on the other hand, are easy to operate and we’re pretty sure that nobody will have trouble with figuring out how the pump works.

  • Hygiene

The fact that S2 is a closed system makes this model very hygienic – the parts that come in contact with the milk aren’t exposed to any sorts of infections. The connector and the breast shield are all one-piece, and the cleaning instructions are easy to follow and not too complicated. Unfortunately, you cannot put this pump in your dishwasher – you’ll have to wash it by hands.

What’s wrong with the product?

  • Portability is hampered by the lack of batteries

The Spectra S2 is an electric model – and that’s it. You cannot use it without a nearby power source, as it lacks the built-in batteries that would allow you to use it anywhere you want. We hope that the guys and girls from Spectra will fix this in the next revision.

  • It’s not dishwasher safe

Cleaning this model isn’t a hard task, but it’s a shame that it’s not dishwasher safe. You’ll have to carefully wash each piece of it by hands, which could take a long time.


Although Spectra is quite new to the American market, we can already predict a bright future for the company. The S2 is among the best electric models we’ve ever seen since it comes with a lot of useful features and using it feels incredibly comfortable and convenient. We didn’t like the lack of batteries and the fact that it’s not dishwasher safe, but these are just minor disadvantages when compared to the pump’s overall efficiency, comfort, and speed. We liked it!
