About a week ago, I went to a consignment sale and purchased a Lansinoh double electric pump that I planned on using at work and in the car so I could keep my larger pump (Medela Pump in Style) at home. I purchased all the replacement parts and I tried using that pump yesterday to make sure I knew how it worked...OMG! Not only did it have too many pieces to put together, but it was SO uncomfortable! I'm glad I only paid $35 for it, but it looks like I'm going to have to tote my large Madela tote bag around. but I'm sure I'll get used to it!
