took less than 10 minutes for front and back replacement: a lot of that was spent on figuring out how to get rear wiper removed. perfect fit. by geometry, installing passenger front wiper was a little more tricky simply because of the reach issue [and I have long arms]. but that's not a problem with the wipers. windows were covered with pollen. using the spray and wipe option, they cleared up beautifully in one pass. note: OEM has a heavier bow with a joint in it to adapt to window curve. this wiper has a lighter, more flexible bow with no joints, but hugged the window perfectly. it may help that it's almost 90 F outside. waiting to see how it does in colder weather and with snow, and to see durability.

These wipers are fantastic. They were easy to install and conformed to the windshield perfectly. Did a great job wiping the rain away. Best thing of all is they lock into place on the wiper arm.
