7.0 / 10Worth it with conditions
Based on published reviews, not our own testing.
BabyGearLab named it its Best Manual Breast Pump after it expressed more milk per minute than any manual pump and some electric pumps it tested, and The Bump gave it a 2026 award for reducing hand fatigue.
Wirecutter preferred the Medela Harmony for easier suction control.
Amazon.sa shoppers rate it 4.4/5 from over 17,000 ratings.
The Amazon.sa price is somewhat above the US list price, and as a single manual pump it suits occasional use rather than daily pumping.
A good fit if
- You pump occasionally, or want a backup to an electric pump
- One of the included flange sizes (25 mm or 30.5 mm) fits you, or you buy the right size separately
- You do not plan to exclusively or frequently pump; a double electric pump suits that better
Product strengths
- Most efficient manual pump in BabyGearLab's lab tests (about 0.28 oz per minute)
- Smooth, easy-to-press handle that reduces hand fatigue, per The Bump's tester
- Few parts, quick to assemble and clean; top-rack dishwasher safe
- Light and needs no power, easy to carry in a bag
- Two modes for let-down and expression, plus a bottle that pumps, stores and feeds
Before you buy
- Pumps one breast at a time, so sessions take longer
- Hand and arm fatigue in long sessions; not for exclusive or frequent pumping
- Only two flange sizes included; others sold separately
- Suction harder to control than the Medela Harmony, per Wirecutter
- Handle can squeak, per BabyGearLab

About the product
Overview
A single-side, hand-operated breast pump from Lansinoh. You squeeze the handle to create suction and the milk collects in a 5 oz wide-neck bottle that can also be used to store and feed. It needs no batteries or power outlet, so it suits occasional pumping at home or on the go.
Key features (per Lansinoh and the Amazon.sa listing)
- Two pumping modes: stimulation to help let-down, and expression for the main flow. You switch by moving the handle position on the stem.
- Two ComfortFit flanges with soft, flexible rims in 25 mm and 30.5 mm.
- Easy-express ergonomic handle designed to reduce hand fatigue.
- Few parts, so it is quick to assemble and clean. Made without BPA and BPS.
- Includes a 5 oz storage bottle, bottle stand, storage lid and one slow-flow NaturalWave nipple, so the same bottle can go from pumping to storing to feeding.
What reviews found
- BabyGearLab (Nov 2023) named it its Best Manual Breast Pump. In its lab it expressed about 0.28 oz of milk per minute, more than some electric pumps tested, with 200 mmHg measured suction. Overall it scored 64/100 among all pumps, with high marks for ease of use (8.2), portability (8.3) and hygiene (8.0) but lower efficiency (5.0) and comfort (5.6) against double electric pumps.
- The Bump (2026) gave it a Best of The Bump award as the best manual pump for reducing hand fatigue, praising the smooth, easy-to-press handle and the soft flange rims.
- Good Housekeeping lists it among the best manual pumps for its comfortable handle, two flange sizes and dishwasher-safe parts.
- Wirecutter tested it but preferred the Medela Harmony, finding the Lansinoh's suction harder to control.
- On Amazon.sa it is rated highly by thousands of shoppers.
Who it suits
- Mothers who pump occasionally: an outing, a few hours away from the baby, or relief from fullness.
- As a backup to an electric pump, or a light pump to keep in the bag while travelling.
- Mothers who want something simple with no motor or charging.
Limits before buying
- Pumps one breast at a time, so emptying both breasts takes longer than with a double electric pump.
- Needs hand and arm effort; testers report fatigue in longer sessions. It is not designed for exclusive or frequent daily pumping.
- Only two flange sizes are included; some testers found both too big, and other sizes (21 mm and 36 mm) are sold separately. Correct flange fit matters for comfort.
- BabyGearLab noted the handle can squeak.
Care
- Take the pump apart and wash the parts that touch milk after each use. Per BabyGearLab the parts are top-rack dishwasher safe, though hand washing plastic is gentler.
- A standard bottle brush cleans the wide-neck bottle easily.
- Let parts dry completely, and follow the manual on when to replace the valve and diaphragm. Replacement parts are available from Lansinoh.
