Here's what other sites are saying:
The SMC PMP is a rescue size pulley that is designed for use in serious rigging applications. Featuring unique shaped sideplates that maximize the effectiveness of the Prusik hitch as part of a progress capture device, its compact size in combination with a larger than usual diameter sheave makes even static rescue ropes easy to manage. The heart of this pulley is a high efficiency precision sealed ball bearing used to counter the performance losses inherent in large pulley systems. The extra large top hole easily accepts three rescue-sized carabiners and low profile fasteners help eliminate possibility of snagging.
