I used my Avent Isis Duo with great success BFing my DD for 18 months and pumping while at work. I really like it and urged others to look into it, rather than just the default Medela.
However, after 2 months of once per day pumping with DS, I'm not getting good suction -- I had spare diaphragms & replaced them (those are cheap) but have come to the conclusion that the tubing needs to be replaced -- I think it's worn/stretched where it connects to the non-control pump. I can't find replacement tubing anywhere but on the official Philips site and it's $54!1!!!!!!! Free shipping, but still, good grief! $54! !!
Does anybody have any experience with this? Is there anywhere I can get it cheaper? Is there any way I could just use Medela replacement tubing (which is $8)? Or some other brand?
ETA: So the pump with its current tubing has been used about 20months. Bah.
