Date added: 01/27/2014Testimonial by: Cesar Ginez of nevadaMr.I have been using a manual pump for about 3 years now and have always enjoyed pumping. I recently received my DP-4000 maximizer and have to say that it is amazing. I have been wanting to purchase this system for a long time and am very happy that I finally got it. The software is very easy to use. Very fast customer service.
