We received the ASCO Red Hat Valve April 8, and were able
to test it April 10. Below, Sarah and and Shannon found it took 35 seconds to
drain 500mL of water through the Red Hat valve.

We received the P-150 Pinch valve on April 18 and have been continually testing it ever since:
The tubing was held in the pinch valve for two weeks, and
carefully examined for any damage signs, such as cracking.
The bag was filled and emptied numerous times to ensure the
valve worked properly, the tubing stayed in place, and the quick snapping shut
of the valve did not damage the tubing.
The bag was actually worn for a day to classes to ensure that
even motion, which is not really a high concern, did not cause any problems
or leaking. The valve and tubing survived walking, biking, and a dynamics experiment...but
the plastic of the leg bag did not fare as well, and the test had to come to
an end.
