interesting that this issue is coming up again for someone else!! I think I resolved my e-flow problems; but, I still occassionally get a wasted vial of med. Probably 2 or 3 in a 4 week cycle...in my opinion, too many.
I'd be interested to see if there are any other complaints. I think what sucks is that those sets are very expesnive to replace. Unlike the pari sets. So it is REAL problem that they leak!!!
