FAQ

Is there a "standard" size?
No. Every woman is unique. Use the included inserts (17, 19, 21mm) to find your fit.
Does size affect milk supply?
Yes. A proper seal signals your body to produce more milk. Bad fit = less milk.
What if I am between sizes?
Choose the slightly larger size to avoid constriction and rubbing.

The 3am feeds used to wreck me. Now I pump in the dark while she settles and it’s so quiet my partner sleeps right through. Totally hands-free, no fumbling with tubes, so I get back to sleep so much faster. Honestly wish I’d found it sooner.

★★★★★
Jessica M.Verified

Between back-to-back shifts and twins at home there’s never a spare minute, so pumping hands-free while I get the nappy bag packed has saved me. As a nurse and a mum of two I’ve tried a fair few, and this is the first that’s quiet enough to use on a busy shift. I recommend it to every mum I meet.

★★★★★
Amanda K.Verified

I’ll be honest, I was sceptical a little wearable one could keep up with my old plug-in pump. My very first session gave me more than I expected and it’s only got better since. Genuinely surprised.

★★★★★
Natalie R.Verified

So quiet I can pump right at my desk and nobody has a clue, even on video calls. It tucks straight into my bra so my hands stay free to keep working. Total game changer for going back to the office.

      Frequently Asked Questions

      Is the S32 PRO2 really hands-free?+
      Yes! The S32 PRO2 fits entirely inside your bra with no tubes or external bottles. You can walk, work, cook, or hold your baby while pumping — completely hands-free.
      Can I use both cups at the same time?+
      Yes — it’s a double electric pump. Using both cups simultaneously cuts your pumping time in half and boosts output through double stimulation.
      Will it suit my breast shape and size?+
      Yes. The fit depends on your nipple size, not your cup size. Relievoo™ includes four flange sizes: 17 mm, 19 mm, 21 mm and 24 mm, plus a nipple measurement guide to help you choose the right one.
      Is it comfortable for long sessions?+
      Soft food-grade silicone + 4 flange sizes (17–24 mm) for a custom fit. Mums pump 30+ minutes without discomfort — no pinching, no pressure marks.
      Will my supply drop if I switch?+
      Mums report the same or more milk. The stimulation mode triggers letdown naturally, and because you can pump more often hands-free, many actually increase their supply.
      How does it compare to plug-in pumps?+
      Same 300 mmHg hospital-grade suction, but completely wireless. No cords, no bottles to hold — just slip it in your bra and go.
      How do I clean the pump?+
      Only 4 parts. Rinse in seconds or toss in the dishwasher. No tubes, no tiny valves to lose — takes under 2 minutes.
      What if it doesn’t work for me?+
      We offer a 30-day money-back guarantee, no questions asked. If you are not 100% satisfied, contact us for a full refund — free UK returns, no overseas postage. Plus, the pump comes with a lifetime warranty against manufacturing defects. All purchases are protected under UK Consumer Rights Act.
      What exactly does the lifetime warranty cover?+
      Your Relievoo™ pump is covered by a lifetime warranty against manufacturing defects — for as long as you own it. If the motor, electronics or seals ever fail under normal use, our UK support team will repair or replace your pump free of charge. No registration and no receipt-hunting — your order number is enough. The warranty covers manufacturing faults; it does not cover accidental damage, loss, or the normal wear of replaceable parts such as silicone inserts and valves (these are inexpensive to re-order). On top of the warranty, every purchase is also protected by the UK Consumer Rights Act 2015.
      How fast is shipping to the UK?+
      We offer free shipping on all UK orders. Delivery takes 3–5 business days UK-wide with the UK Post, fully tracked.
      Is the Relievoo™ pump covered by private health insurance?+
      Many UK private health funds cover breast pumps under extras or maternity benefits. We recommend checking with your fund (e.g. Bupa, AXA Health, Vitality) to confirm your eligibility and claim process.

      The wearable in bra breast pumps that I purchased from Relievoo have been a game changer. I have been able to express on the go and even infront of family and strangers, I've even took the bus and gone to appointments, I even did a driving lesson with them on. Im only 3 and a half weeks in and my milk supply is well established now and I have been able to completely get rid of formula from 3-4days old and now having a considerable stash in the freezer and fridge of milk ready to use. All whilst still feeding my little one at each feed. Im an exclusively expressed breast milk mama. As my lil one hasn't latched since using bottles in hospital. But I'm ok with that as I'm now experiencing a level of freedom I never have previously with my other children. This has given my baby, myself and my family the chance to have the best of both worlds.
