Below is a more detailed info on the Medela Freestyle Flex vs Spectra S2 Plus

Differences Between Spectra S2 vs Medela Freestyle Flex

Let’s dive in a little deeper about the differences between these Medela vs Spectra breast pumps.

Battery 

This is one of the main differences between the Medela Freestyle Flex vs Spectra S2 Plus – its battery. Or the lack of it.

The Medela Freestyle Flex has a rechargeable battery, which is super convenient. Especially if you’re traveling or if you want to do some chores in the house while still pumping.

It’s also easier to use for C-sect moms or those with back pain to use. As you don’t need to bend to plug in your breast pump every time you pump.

You also only need to charge it for 2 hours (for first-time use), to get 2-hour battery life.

There is some mixed feedback though about its battery life, with some moms complaining it doesn’t fully charge or worse, the pump dies on them completely.

When this happens, try pressing on the on/off button for 10 seconds or better yet, request for a replacement asap.

The Spectra S2 on the other hand, doesn’t have any rechargeable batteries. This means you always need to plug it in if you want to use it.

This can become a hassle as you would be stuck to a wall pumping for 15 or so minutes.

Some genius moms have found a way to hack this. 

They’ve advised buying a carrying case and battery pack, attaching the batter pack to the Spectra S2 and voila, you have a portable breast pump!

Hospital Grade 

Hospital-grade breast pumps mean that it has a powerful motor and that many persons can use them, provided that they have their own set of accessories.

This also means hospital-grade breast pumps can be sold and reused.

In this case, the Spectra S2 is considered a hospital-grade pump while Medela Freestyle Flex is not considered as one.

If you’re looking for a hospital-grade Medela breast pump, check out Medela Symphony.

Weight 

The Spectra S2 weighs 3 lbs, which is heavier than Medela Freestyle Flex‘s less than 1 pound.

The weight difference can become a factor if you’re looking for something lightweight for pumping on vacations or business trips.

Price 

The Medela Freestyle Flex is much more expensive than the Spectra S2 Plus.

You can get some open box options though for the Medela Freestyle Flex, at a cheaper price. 

You can also find some gently used Spectra S2 online, at a much lower price.

Warranty 

The Spectra S2 has a 2-year warranty on its motor and a 90-day warranty for its accessories that came with the breast pump.

Just make sure to buy it from a legit third-party seller or straight from the Spectra website itself, so they can honor the warranty.

Take note that Spectra warranty is only within the United States

The Medela Freestyle, on the other hand, has a 1-year motor warranty and a 90-day warranty on its accessories.

Insurance

Not every insurance fully covers breast pumps.

So you have to check with your insurance company if they can fully or at least partially cover either your preferred breast pump before buying it.

Spectra S2 Plus is usually fully covered though but still, check first with your insurance.

Nightlight 

The Spectra S2 Plus has a built-in LED nightlight with 2 lighting levels. Which is useful when you’re pumping in the dark.

The Medela Freestyle Flex doesn’t have a nightlight but its motor control units do light up when it’s switched on.

And those are the differences between the Spectra S2 vs Medela Freestyle Flex.

Motor/ Suction Rate 

Both the Medela Freestyle Flex and Spectra S2 Plus have mixed reviews about their motor, more so for the Medela.

Some moms say that both have great suction power. While others are complaining that both have very poor suction and gets relatively weaker after only a few months of use.

Some said you can’t even use both for pumping after only a few months! So it’s really a mixed bag of motor reviews.

For example, some moms said the Spectra S2 lets them empty out in only less than 5 minutes, getting 4oz on each side.

Other moms, however, mentioned that they can’t even get a decent amount of milk, even if they’ve adjusted it to the strongest suction level.

Same mixed feedback as well with the Medela Freestyle Flex. For eg., one mom shared that she can even get 200ml of milk for about 15 minutes.

While some complained that it can’t even go to the maximum suction rate and its suction power gets weaker and weaker after only a few months of use.

Adjustable Settings

Both the Medela Freestyle Flex vs Spectra S2 Plus breast pump has adjustable settings or pumping modes, to suit your preferred suction power and pumping speed.

The Medela Freestyle Flex has the Stimulation phase and Expression phase. The Stimulation Phase is to stimulate milk flow, while the Expression phase is more for efficient and steady pumping.

Both can be adjusted from L1 up to L9. However, the Medela Freestyle doesn’t have any speed setting. 

Which means you can’t control the speed of pumping.

All the suction and speed settings can be controlled via a separate motor unit, which beeps after 15 minutes, reminding you of how long you’ve been pumping. 

This control motor unit can be connected to the MyMedela app, to help you track your pumping sessions, record the sleeping habits of your newborn, diaper output, and more.

The control motor unit though is a bit sensitive and it can easily change your settings accidentally. It can also become unresponsive at times, according to some moms.

The Spectra S2 Plus has the Massage and Expression mode. The Massage mode is used for stimulating a letdown while the Expression mode is used after, for a steadier pumping.

The Massage mode can be adjusted from L1 to L5, while the Expression mode is adjustable from L1 to L12.

The Massage mode has only one-speed setting while the Expression mode has a 5 cycle speed.

Comfortable

Both these Spectra and Medela breast pumps are relatively comfortable to use.

Moms have been commenting on how much more gentle and comfortable the Spectra breast pumps are though, compared to the Medela brand.

Quiet

Both the Medela Freestyle Flex and Spectra S2 Plus have a quiet motor, comparable to the noise level of a hushed library and a muffled conversation in a quiet suburb.

Which is discreet enough for you to pump in the dark while your baby sleeps or behind the closed door of your office.

Some parents though find both a little too loud for their taste, more so the Medela than the Spectra.

Easy to Clean 

Both the Spectra S2 vs Medela Freestyle Flex breast pumps are easy to clean, but more so the Spectra than the Medela, according to some moms.

Universal Voltage

Both the Medela Freestyle Flex vs Spectra S2 have the same universal voltage of 100V-240V / 50-60Hz.

That means you can use it in another country!

Do take note to get an adapter if you’re traveling abroad, as the outlets there might have a different plug shape.

AutoTurn Off 

Both these Medela and Spectra breast pumps automatically turn off after 30 minutes of pumping.

Accessories 

You can easily buy accessories or replacement parts online for both the Medela Freestyle Flex and Spectra S2 Plus. They are readily available on Amazon, Target, Walmart, BuyBuyBaby, etc.

Here are more accessory related tips as given by other moms online:

  • Measure and get another set of flanges or breast shields, as the one that comes with the set might not fit you
  • A hands-free pumping bra will save you time to pump and do chores or work at the same time.
  • Get a carrying case for your breast pumps, so it’s more convenient to lug them around anywhere
  • Spectra is compatible with Medela and Avent storage bottles
