Which is better for electric breast pump?

I think avent's is good. I bought an unknown electric breast pump before I was born. After I gave birth to a good baby, I couldn't suck it out at all. . .

It turns out that breast pumps also have principles. For example, avent has a massage cushion on its speaker, which can stimulate the breast array without fear of radio frequency damage. Just press the handle a few times, you can see several milk lines, and you can suck them to both sides in about 20 minutes, which is very easy.
