Sorry I haven't heard of them or used them. (Well I probably have heard of them but as I have pg brain at the moment can't think).

My friend recommended the Avent ISIS iQ UNO Electronic Breast Pump so this is what I have won't know if it's good till I have bub.

Good Luck picking one. I guess what is good for one person doesn't work for another so makes it hard to buy. Shame you can't try before you buy.
