eufy Wearable Breast Pump S1

I recently purchased the Eufy S1 Pro wearable breast pump and am extremely dissatisfied—not only with the product’s performance but also with Eufy’s handling of my return inquiry.

From a product standpoint:

The flange sizes are too small, making pumping painful and uncomfortable.
It is difficult to properly position and keep my nipples in place, even when wearing a firm, well-fitted bra.
The heating feature is overhyped, adds no benefit, and only worsens the already disappointing battery life.
The unit is too heavy for a wearable pump, especially compared to Medela’s options, which are both lighter and more efficient.
The customer service experience has been equally frustrating:

Instructions for returns are unclear and require navigating a convoluted ticketing system.

After contacting support via the Eufy app, I was told that as long as the product was undamaged it would be refundable within the 30-day window (regardless of reasons), only to be redirected to Eufy Australia for further processing.

Eufy Australia then denied my return due to “hygiene reasons,” a policy not disclosed clearly at the time of purchase and seemingly inconsistent with what I was previously told.

The conflicting information between Eufy teams is confusing and unprofessional. I feel misled and trapped into keeping a product that is both costly and ineffective. If a customer is unhappy with a high-value product—especially one as personal and health-related as a breast pump—there must be a clear and fair way to return it. Trying a pump is the only way to know whether it works for one's body, and Eufy's policies disregard this reality entirely.

I expected better from a brand that charges a premium. Unfortunately, I cannot recommend the Eufy S1 Pro or Eufy’s customer service to other parents.

Very loud ticking sound in both pumps. assembled correctly. Tried getting in touch with Eufy, no response.

The pump was delivered super quickly, with a stress free set up and it's very easy to use. Cleaning the pump and assembling is straight forward.
The app could be a little more user friendly. Unable to change entered data, doesn't always sink both pumps and always have to select which pump I have when entering data (This should automatically save your info.)

So unhappy, this pump is painful to use and gets terrible output.

I have tried flange sizes 17mm, 21mm and 24mm and all rhythms, this pump is only bearable when the suction is low. Even with level 7 suction and on ‘Max Rhythm’ setting, the output is soooo much less than any other pump I’ve used.

The heating feature is temperamental, even when the pump is assembled correctly.

The pump is not quiet, I wouldn’t dare go anywhere in public unless with this on.

This product is so overpriced and not worth the hype, any reviews online that I was able to find after purchasing this product were sponsored and any that weren’t were negative.

This company is not decent enough to accept refunds.

DONT WASTE YOUR MONEY!

I want return but when I contact with eufy . Nobody reply back to me.I’m not happy
