Cons
✗Bigger and heavier than Medela
✗Bottles are non-standard (need adapters for some brands)

The verdict

So which one should you get?

Spectra S1 wins for most NYC moms: rechargeable battery (pump on the subway), closed system (more hygienic), and gentler suction that LCs prefer. Medela still wins if your insurance covers it fully or you need the fastest pump speed for short office breaks. Check your insurance — most cover one free pump.
