My partner & I have a Medela pump rental station. We had all our Lactinas as Plus until the Select came out. For long term rental moms we traded them a Select for their Plus and got nary a com- plaint. In fact one of the moms was so thrilled with her Select, and told people far and wide, that a friend of hers traded in her Plus to another rental station and came to us for a Select.
