Yaffa ,
Thank you, thank you, thank you.  I rent Ameda/Egnell pumps, and am convinced
that the Lactina is not as effective as the classic, nor is the Lact-e lite as
effective as the Lact-e.  Have seen too many mothers with dwindling milk
supplies because they were using the wrong pump for their situation.  I allow
refunds and trade ins (except for the sterile kits) for this reason, to get
the best fit possible between mother and pump.
