I run Silblade wipers. It's about $50 a pair, but they will last years, which more than offsets initial cost. The only thing that will kill them is if you abuse them by using them a lot with your window dirty with bug parts or ice, that will eventually wear the blade surfaces. I have no reason to promote them other than the product works extremely well.
They will likely last 5 years at least, the company brags that time range and I had a set on my previous vehicle that went past that. If they last 5 years that is $10 a year, how many sets of normal blades will you change a year for $10?
Silicone is an amazing substance. It doesn't degrade in sunlight, and it doesn't care if it's hot or cold (within any temp range a human can survive.) After experiencing how well the wipers held up, I used silicone in the padding of my roof rack mounts and it's lasting perfectly despite the wide range of weather it has been subjected to.
I also do the Rain-X washer fluid, I think the silicone substances in the fluid and the silicone blades compliment each other and make the window even more hydrophobic.
My only issue is bug guts build up and cause a film a bit worse because it spreads on top the silicone layer, but I give it a quick once over at the gas pump and it's good. I only have that issue in spring/fall when bugs are horrible here in KY.
