From the seller

selling my spectra S1 plus Months used - 5 months (277 hours - photo as proof) Condition- excellent, all parts available, video showing everything Reason of selling - Switched to formula some months back due to resuming work Location - Bangalore Pros of the pump- Helped build my supply from 700-750 ml a day to 1L to 1.2 L a day with only three pumps a day (of course supply is also determined by other factors like sleep, water and calorie intake, personal factors etc but stating my example), maintained a freezer stash, very long battery life ( I charged it once in three days) , spent very less time pumping as compared to luvlap, excellent suction capacity, multiple modes- honestly the best investment one can make if they are exclusively pumping/ looking to build freezer stash/ boost supply Cons: expensive, do not purchase for occasional pumping, cannot be used while traveling to office etc- you would need a hands free one
