Again, no idea about the sour milk thing as I still haven't had that problem yet. My son is currently 10 weeks old and he's been super healthy since birth. And I add fresh to refrigerated without warming all the time. I also sometimes refrigerate an already warmed bottle, rewarm, and feed it back to him later on in the day. No problems yet.
At any rate, here's some info on the Whittlestone Manual Expresser...

What is an Expresser? A newer and better way to express your milk. This technology replaces all existing breast pumps on the market today.
What makes the Expresser “a breakthrough in breastfeeding technology"? Two Things: Pulsation and One-Way Airflow
Pulsation: Vacuum moves milk from the breast while expressing. Vacuum also causes “congestion” to form at the front of the breast, which can be very uncomfortable We designed our breast cup to gently pulsate the breast with every handle squeeze to help relieve this congestion. Pulsation is exclusive to Whittlestone. Why I should care? This unique combination of Pulsation and One-Way Airflow gives you the following:
One-way Airflow: Our unique air-flow system does not allow material to be pushed back towards the open nipple ducts while expressing, therefore “ideal” for helping maintain a clean environment at the breast. One-way Airflow is exclusive to Whittlestone.
Speed: Ultra fast, saves you time.Are there any other benefits with the Whittlestone Expresser? Yes, there are three other important features:
Comfort: Relaxing means faster let downs. Encourages longer lactations.
Protection: Designed to create a healthier environment at the breast.
Vacuum dial: Allows you to choose your perfect comfort setting…others don't!
Fits all breasts.
Simple to use…easy to clean.
