As a first timer, I bought this before baby arrived and wish I had waited to get a better understanding of what pumping really entailed, and which features mattered before making a purchase. I ended up borrowing a hospital grade pump and much prefer the fitted flange to the universal sized one included in this one. Also, the whole pump/bottle apparatus is rather bulky and awkward to maneuver within a pumping bra (the outside piece has to screw onto/off of the flange instead of the other way around, if that makes sense, meaning that you spill milk afterward when trying to remove from within your bra).
I ended up keeping the hospital pump flange/collector setup and just hooking the tubing up to this one.
The suction itself is great and I like the different settings. I would advise first timers to speak with a lactation consultant for some fitting recommendations before springing for a pump to make sure you get one that fits you best!
