Frustrating but effective
"I purchased this pump to use primarily at work after maternity leave. I need to pump 3-4 times while at work. I wanted a pump that had good suction and could store in the fridge between pumps, eliminating the need to fully clean and sanitize between pumps the same day. This pump design creates an issue in that if the gasket gets milk residue between pumps it causes the cups to separate, spilling all the milk. It is pretty frustrating. I understand that the instructions state the parts must all be dry but I wish something would’ve stated very plainly that this eliminated the refrigerator storage method."
