Don't waste your money
I purchased these from the momcozy website but they don't allow you to leave a review, so I'm going to do it here. Do not buy, I bought a set of the M1 pumps and have been using them for a week and started having issues right away. The customer service is a joke. They do not help, there is no return policy essentially. If you open the product you can't return it and it also voids any warranty on the product if you open them, makes a lot of sense. Not. One isn't holding battery as long as the other, they change modes consistently while using, and recently the pump portion with the buttons has been getting very hot after using for a few minutes. Also a draw back, I put them in my diaper bag (with mainly soft items inside, diapers, burp cloth etc..) and one of the pumps button control area is all scratched up, so clearly scratches easily. I wish I could return these. They're not worth the money. Spend the extra $100 or so and get the Willow Go instead. Stear clear of this company. Idk how it has so many good reviews.
