PowerPull oar locks


East Fork

Has anyone had experience with the PowerPull oar locks distributed by Don Hill Drift Boats(www.dhdriftboats.com)? I read a flier at the boat show that claimed they were 30% easier to use than standard oar locks. 30% might be enough to justify the $150 price (Ouch!) but is it real? I need some real world feedback before I spend the money. Thanks in advance.
