Isis uno, duo and single

[jellyjelly]

What is the difference between them all?

I must assume we are talking about the avent breastpump range? forgive me if were not....
the avent isis is simply a manual hand pump-no battries or mains.....the avent isis iq is a manual handpump that after you pump for a bit, it memorizes your pumping rythum and pumps for you-not 100% sure if this is battries/mains or both and a duo is oviously a double pump....hth a bit? (excuse the poor spelling)

thanks i have 2 manual isis pumps but wanted to know about the new and imrpoved one.
