For what it's worth, I have a PIS and rented a lactina for 2 months when latch issues led to supply issues. I couldn't really tell the difference, personally, though it's been a while now. Plus, the expense was greater than just the rental cost, since I needed the different style of tubing, etc. The cost was over $100. My understanding of the difference in recommendations was related to longevity of the motor -- that the Lactina could handle a years+ worth of pumping 8 times a day, while the PIS could not. *********************************************** To temporarily stop your subscription: set lactnet nomail To start it again: set lactnet mail (or digest) To unsubscribe: unsubscribe lactnet All commands go to [log in to unmask] The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(R) mailer for lightning fast mail delivery.
