Just received my order today, can’t wait to try it out. Cleaned, sterilized and charged it before use. It is easy to assemble and use. Probably won’t use any other pump again. I would say this is the best investment I made for breastfeeding. It is powerful yet gentle and comfortable. I can pump just as much if not more than my spectra medical grade pump. This will be a great for mums who is returning to work as you can pump anywhere and anytime without having to carrying a pump with cords and bottles. High recommend, price was reasonable compared to similar ones on the market and arrived quickly.
