K.W.
I have read all of the responses to your email M.. I certainly understand your reluctance to sell and your investment just sitting there unused.
I have an unpopular response to your question.
First, no it isn't gross to want to recoup some of your money. I know a lot of women who get second hand pumps and new kits.
Here is the difference in rental and pumps you purchase, the rental pumps use a suction system that doesn't allow for any interchange of body fluids thru tubes or otherwise and can be "sterilized" not just cleaned with alcohol that can still allow some bacteria to regrow.
Medela was SUCCESSFULLY sued in a court of law re this reuse of personal pumps and are required to tell all customers emphatically that you can transfer bacteria and fungus from storage on a used pump to the next person even with new sterile tubes and shields etc. We live in a culture that wants to make all business money grubbing bad guys. Most are not like that underneath, simply trying to cya in a very litigious society.
I am trying to present, although unpopular, a balanced point of view.
So now it is up to you. There is my opinion. (and yes I do sell medela pumps and that has no bearing on my response to you since I also sell the parts)
Sincerely,
K. @ The Nestingplace, Grapevine
