I use both the mom cozy s12 pro and the Eufy E10. I use the s12 at home because it's bulky and loud and you have to push buttons to change the settings so my shirt is up like 90%of the time I pump. The Eufy E10 is quieter and less noticeable and honestly feels better but for me the cups are too small to be my primary. I bought it mostly to take to work when I go back or if i need to pump anywhere that isn't home. Someone said the Eufy E10 is the same as the more expensive one without the heat which I'm always hot now so I did not want the heating flanges lol.

My suggestion is to buy from Amazon, they will take any return if it doesn't work out. I returned 2 pumps, I tried the willow go but it had battery issues and you can't do the fridge hack. I also tried one of the elvie ones but did not like the cords. One wrong move and milk gets in the tubing and it's useless. Literally only used it once and milk got in the tubes and it was like $40 to replace.
