Here's the scoop. I personally tested the new Limerick Pj Junior and found it to be easier to let down to than the PIS. With the PIS it took me about 15 minutes to let-down. With the Limerick it took about 2 minutes and I had multiple let downs. I noticed that my milk supply increased rapidly as well with the Limerick.
As many of you know, I'm currently studying for my doctorate which required time away from my still-breastfeeding son. While travelling to doctoral seminars or conferences, I brought my PIS because it has a battery pack option, and pumped everywhere....on planes, in restaurants and in class (with advanced permission). Although I was diligent, my milk supply would suffer partly due to my schedule and partly due to the stress of presenting doctoral products and so on. By the time I would get home, I would be in a bit of trouble, even with Ethan back at the breast. As soon as I started pumping with the Limerick, ZOOM my milk supply would shoot up again within a couple of days.
I started travelling with the Limerick and a long extension chord and my milk supply remained constant, no more dips.
What is great about this pump is that it has flexible breast shields that compress the nipple/areola while suction is applied thereby producing both positive and negative pressure to the breast, much like a baby does.
The price is right too, and the pump has a built-in timer so you don't have to watch the clock which is also nice because when you start breastfeeding, you don't want to be watching the clock either.
And it's rated as a multiple user pump so you can re-sell it later, all the person needs to do is purchase their own breast shields and tubing. There is a filter that prevents backflow of milk into the pump and it has a three pronged plug ie: it's hospital grade!
The contact for the Limerick is
joan.ortiz@limerickinc.com Note that I do not receive any renumeration from this company and I purchased the pump I tested. Their service is wonderful as well.
So there you have it. My first choice is the Limerick and my second choice is the PIS. But both will do the job.
Best,
