I use my harmony to exclusively pump. I find that it is quicker and more efficient than my Pump in Style Advanced. The only drawback is not being able to find replacement orings. Love the convenance and portability of this pump. If I wear a pumping bra I can let go and tend to my baby if needed then pick up right where I left off.

I bought this for traveling but it doesn't work n I can't return this product so it's completely waste of money my honest review is not to buy this garbage

I used this 2 times and it was great! Third time… no suction! Best I can figure out is the o-ring may be missing. Why would this just randomly come off so soon?

I started out with the electric automatic pump ( can’t remember the name) and after the 30 minute sessions I was so sore and my milk supply just kept dropping. My first born couldn’t breast feed. With my second born I’ve been using my Harmony pump on the side he isn’t on and holy crap… I can get the full breast cleared out in a matter of 5-10 minutes and it’s painless. It’s amazing with the silicone edges because it’s more comfortable. I would recommend getting a duck bill flange for the inside because I feel like it just has better suction. It’s amazing for the car, for quick night pump sessions and just for every pump session really. I know it’s only one breast at a time but it’s so much quicker. I didn’t think pumping would be possible with two under two and one of them having complex medical needs. Just buy this, you seriously won’t regret it. I don’t even touch my automatic pump anymore.

I'd like to give this product a higher rating, because it's much easier to carry to work than my electric breast pump and I can express more milk in less time on both sides. However, it only comes with one 24 mm shield and that's too small for me. I can't find a 27 mm shield to purchase separately except for suspicious-looking knockoffs on Amazon. It shouldn't be such a pain to get a shield that actually fits my nipples. So for work, I have a choice of lugging around a heavy electric pump on the train, or using the manual and having my nipples hurt for hours. Neither one is great.

Comfortably transportable and not exhausting to use. The only thing I find inconvenient is that it only screws onto medela bottles. Cannot pump directly into a dr browns

This is such a handy breast pump and very easy to take wherever I need to take it!

[This review was collected as part of a promotion.] I never write reviews but here I am. This is by far the best thing that happened to me postpartum lol. I hated “pumping time” so much because it was painful and took all my time but I tried this hand pump and in less than 10 minutes I got more than what I get with my electric one and with less pain
