I think my PISA is crapping out on me. The dial to adjust speed/pressure is acting funny. I was at Target last night and they had an Avent Isis IQ Duo on clearance. I would assume it is due to the bottles packaged with it not being the new BPA free ones? Also I use Avent bottles so being able to pump into the bottles we use would be nice since BRU pulled the adapters just as I found them and wanted to buy. Just wondering if anyone else uses an Avent pump, how you like it, and if possible compare to the PISA.
