I'll admit that I haven't had the chance to use this pump yet, but I give a glorious review to the company because they really give superior customer service. I was very impressed and surprised to interact with one of the people at this company - he was super helpful and I was so blown away to actually get a human response during an online shopping experience these days!! No black hole here - Real communication and real service!!! I will be coming back to this company for many years to come!
