easy install, cleans well
Size: 26" 20" 12"
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.

Would buy again
Size: 26"/14"/12"
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.
