Maybe this post comes a bit late. I've been using Spectra 9+ since late January 2016. It's a portable pump which can be brought around conveniently. These are my reviews after using it for almost 1 month:
-Suction less strong than other pump. Eg: Medela
-The sound level during pumping is quite loud especially during very quiet night
-The breast shields are quite big & one must hold properly during pumping otherwise milk will leak out
-Pro is this pump comes with a self timer which will auto shut off after 30 mins. The small screen will also show the battery level. It has to be charged after 4 - 5 times usage. Price is low at $120+ selling at Qoo10.
I hope these information helps.
