Some breast pumps are like workhorses: less streamlined than others, perhaps, but able to perform at the highest level, consistently, for days, weeks and years. It’s that sort of breast pump that becomes invaluable when expressing full-time – eight times a day, seven days a week – for a premature baby, or to keep your supply going when your baby struggles with her latch. This is where the Spectra S1 comes into its own.
Our parent-tester Zanna first tried a rented Spectra S1 breast pump when her daughter was a newborn after a tricky start to their breast feeding journey.
My daughter lost too much weight during the first few weeks so we had to triple-feed her. I honestly think that the Spectra S1 was the only reason I was able to continue breastfeeding. It's powerful, doesn't leak and is super-efficient.
How big is the Spectra S1?
One of the only downsides of this impressive breast pump, especially when you compare it to some of the wearable pumps on the market, is its size. While the base unit measures a fairly substantial 20cm x 20cm x 17cm, the pump itself weighs less than a kilogram. 'I wouldn't take it on a plane or anything,' Zanna said. 'But I've taken it on a few staycation holidays. I also have a MomCozy M5 wearable pump and that one is a lot smaller and more portable.'
How easy is the Spectra S1 to set up and use?
'It's very easy to set up and use the Spectra S1. The only slightly tricky aspect of first setting up were the valve attachments, but once I got my head around them, it was a breeze.'
What's the Spectra S1 like to use day-to-day?
'I used the Spectra breast pump daily for the first six months of feeding my daughter,' explains Zanna. 'It was brilliant. Unlike other pumps I've tried, it never leaked, fitted me well and when I used it with a pumping bra, I could do things like the washing up thanks to its portability.
'The Spectra slotted into my routine really well, when the baby went to sleep I'd pop it on, pump for 20 minutes and get about 120mls of milk, enough for a bottle-feed. I'd pump both sides at the same time and found it really powerful and efficient without being uncomfortable.'
The Spectra S1 vs Spectra S2: what are the differences?
While the Spectra S1 is slightly more expensive (£160 vs the S2's £126) and slightly heavier (1.5kg vs 1kg) than the Spectra S2, the main difference is that the S1 features a rechargeable battery, making it more portable that the S2 - a feature which parent-tester Zanna found particularly useful.
How easy is it to clean?
'Very easy - I'd hand wash it and then pop it in the steriliser when my daughter was under six months. Now she's older I just hand wash it. It's easy to take apart and put back together.'

I used a Spectra S1 double pump for both my children. I used a couple of different pumps prior to buying the Spectra. The Spectra got me the best yield out of them all, and it did it in half the time. Also make sure you are suing the right flange/funnel size. A correct fitting pump will give you better results.
We asked Zanna to rate the Spectra S1 out of five for the following:
Value for money: 5
'Like I said, this breast pump was a game changer for me, it made it so much easier to keep breast feeding my daughter and I honestly don't think I'd have been able to carry on doing so without it. It's worth every penny.'
