Query: Disappointed

At first, I was really impressed with this product. I was using it multiple times a day when I got back to work. Then, inexplicably after 6 weeks, it stopped working. I bought a second one. 6 weeks after that, the pump lost suction. At $120+, I am unable to afford another. Due to the mediocre quality of this product, my milk is starting to go dry, as it will not provide adequate suction to maintain my supply. I bought this one from a friends recommendation--my own recommendation is to look elsewhere and try other products.
