I had one of this pump previously but it stopped working so I reordered another one. The suction on this bad boy is incredibly and it surprisingly has a great battery life. Certainly worth the buy.

Let me start off by saying this is my first Amazon review I've ever made (that I can remember or think of anyway). I'm a first time mom and did a lot of the care for my baby alone because my boyfriend returned to work (night shift) when our daughter was just barely 2 weeks old. I had the Medela Pump In Style pump but it was difficult to manage pumping every 2-3 hours while also feeding every 2-3 hours and consoling her while crying in between. I ended up going too long without pumping and it took a toll on my supply. I went from pumping 4oz per pump to barely getting 2oz. I purchased two of these before i knew they offered a double pump option. Now, I'm able to pump and feed my 3 month old daughter every 2 hours (at the same time). My supply has gone way up to where I'm pumping 6-10oz per pump session and now have built a pretty decent freezer stash. The suction power is great. I rarely can pump at the strongest level (9). I start out at 1 then gradually increase up to 6-7. The noise level isn't silent but it's not so loud that it'll wake your baby - at least doesn't wake mine up. It's nice to travel with. You can assemble them and put them in your pump bag without them taking up too much room. I can pump in the car, in the store, while I cook, while I get ready, anything. It's soooo helpful. The battery life is pretty decent as well. I pump until empty which usually takes about 40-45minutes each session. I can pump twice before they die but I keep the routine of just plugging them in after I put my milk away. They are a tad bulky but I don't mind it when their benefits are far greater. I'm a full C cup and I have no problem with them fitting properly or getting them into my nursing bra. My sister, who's an H cup, was able to wear them comfortably as well. She just ordered herself some to have the same freedom I have with managing pumping with other daily duties. So break them down from pro to con:

Pros:
Strong suction, convenient, portable, decent battery life, helped increase my supply and give me freedom and the ability to care for my baby all while building up a supply for her to continue breastfeeding in case my supply greatly decreases.

Cons:
Tad bulky, don't know how I'll be able to replace parts without having to buy a whole new set of pumps, the memory function is unnecessary (it'll stay at the suction level of where you finished pumping unless you manually bring it back down to 1 yourself. Sucks your soul out of you chest when you forget to do so.)

UPDATE: I found replacement parts on Amazon do there won't be a need to repurchase the pumps again!

Sometimes leaked and the breast milk gets everywhere.

These are a great alternative to a regular breast pump, especially for the price. They make it so much easier to do things while pumping and the suction is strong. I don't notice any less output with these vs normal pump, if anything they work better. The only downside is the cleaning and assembly. Every part gets milk on it (except the top with the buttons), I spend probably a half hour total each day cleaning all the parts, drying, and reassembling the pumps which is a pain. Luckily I only pump once a day. If I was an exclusive pumper I don't think I could do it with this style of pump. However, for me, the pros outweigh the cons!

I was recommended this product by a friend. As a new mom trying to juggle regular day to day tasks and needing to pump- this was a game changer for the fraction of the price of other hands free pumps! The suction is great, the charge lasts a good time, and my milk supply has increased since being able to add this to my routine, and while clean up does take time, it makes up for the time I'm able to move around while pumping to do other things. I highly recommend this pump!
