A Spectra s2 electric breast pump can last up to an incredible 1500 motor hours before the motor starts weakening. This gives you quality breastmilk pumping time. More so, you should get a new one rather than a second-hand. This is because a second-hand one is already nearing the end of its lifespan. More so, you should know that your breast milk pump lasting long depends a lot on you too. You have to use it carefully. Do not place it within your kids’ reach. Make sure you wash thoroughly after every use. It you do these, you are good to go.
