Got this to just use occasionally based on the reviews as never heard of the brand and I love it! Would really rate it. Great that you can charge it and use on the go or just to do things round the house while you’re pumping. Not sure how good it would be to help establish supply as that’s not what I used it for but if you’re supply is good and you want to pump extra to have in the freezer or something then definitely worth the money. Easily cleaned and stored and takes up way less space compared to a lot of the other pumps.
