Two other things to consider: One size DOES NOT fit all! And comfort is important! The pumping enthusiast will need to consider the diameter and insertable length of the cylinder. He may also want a silicone sleeve for the base of the cylinder. Cylinders come in an astonishing array of sizes and shapes. Be sure to get the right size for the job at hand. If your pump doesn't come with a stretchy rubber, or jelly-like donut attachment at the base of the cylinder, you might consider buying one of these mommas. They add comfort and a level of safety to pumping. They also help create a tighter, more secure vacuum seal.
