Do most mums have 2 pumps? One for home and one for office?

I have 2 pumps. Spectra S1 for home use and Spectra 9+ for outdoor use. Spectra S1 is a hospital grade pump and weighs about 1kg, but it's bulky. If you don't have to carry it to and fro, then you can consider getting one to put in your office. If you have to bring it around, then 9+ is a very good choice because it's lightweight and portable. It also has a rechargeable battery inside which lasts 2 hours on a full charge.
