Has anyone used the Haakaa Breastpump?

I breastfed my first for 14 months before weaning, but with this next baby (due 9/30/18) I will be going back to work sooner and know there will be a need to probably boost or support my supply earlier to build up some frozen extra milk.

I was told by a friend about this product and have read a lot of reviews and am excited to use it! I bought mine on amazon for $35.

It DOESN’T take the place of an electric breast pump, but you can use it during feeding on one side while baby is nursing on the other.. reviews say it’s also good for the diaper bag if you are out and become engorged and need some relief, but don’t want to waste the milk by hand expressing into a sink.

Has anyone tried this product, and what do you think of it? Comments? Reviews? Tips?

I am thinking I will start using it when baby is a few weeks old once we have gotten nursing down (it took me a bit of time with my first to get nursing figured out because she was born early and didn’t have the sucking instinct right away..hoping it will be easier this time around).
