I don't know if anyone has tried these yet on a Prius. On Tire Rack, they have very good reviews: https://www.tirerack.com/tires/tests/testDisplay.jsp?ttid=231 It looks like a great all-season tire, one of the best performers all around. If I expected to drive the car in the snow and did not have a dedicated set of snow tires, these would be at the top of my list! However expect worse fuel economy versus one of the truly low rolling resistance tires like Michelin Energy Savers or Ecopia 422s.
