Cindy,
Most of the mothers I rent pumps to are working moms and I've noticed that
they prefer the Select over the Plus, possibly they are able to express a
little more quickly. A couple of the moms had previously used the Plus and now
prefer the Select. No mother has complained of any Select not having enough
suction.
