What level vacuum do you use on the spectra? Do you ever use the massage function? How many minutes do you use it for?

Use the Massage function to elicit a letdown. Once you have a letdown, switch to Vacuum function at the appropriate suction power. Once your flow has died down again, switch back to Massage function to elicit a second letdown. Do note that subsequent letdowns may take a longer time to elicit. Switch to Vacuum again to drain the milk from breast. P.S. Turning on Massage function for too long can drain battery power.
