I dont know how it is in the US, but in the UK you rent pumps
I have the Momcozy M5 breast pump and it works perfectly for me. I ordered from Amazon and they are good with returns if needed!
You may also be able to rent a hospital grade pump like Mendela pumps. You just have to check with the hospital and your insurance may cover it
I had a momcozy v1. Didn't like it. They just refunded me when I explained my issues
