N.M.
The most Medela In Style Advanced pump was the one that worked for me. It was the one with the electric pump in the included bag. It was painless, it was quick and very efficient. Which is really important in a breast pump. I went through 3 or 4 different pumps and ended up getting this one anyway.

If you plan to have other children this will also be worth every penny. I used every single thing included in this pump. I plan to use it with my next baby.
Its even quiet so when my son woke me in the night to feed I would put him back down to sleep and then pump before I went back to bed without waking up my husband.
Truly a great investment.
Hope this helps!
