The integrated wind spoiler design increases the down force on the wiper blade to prevent lift-off at highway speeds. The bracketless design and enclosed tension springs provide superior wiping performance in all weather conditions. Bosch ICON blades are the best you can buy!

Where the rubber meets the road5
For more than 30 years, I've searched high and low for the perfect wiper blade. Being a little tiny bit obsessive about my car, one of the things I can NOT tolerate is a chattering, noisy, smeary, streaky wiper blade. Driving in the rain is hard enough without feeling like you're trying to look through a wax-paper windshield.

In the past, I'd put new wiper blades on my car two or three times a year and sometimes more, just to make sure I never had to deal with wiper smear or worse, wiper chatter. That sound is like fingernails on a blackboard to me!!

I'd also clean the rubber edge several times between blade changes, to keep the leading edge clean and free from debris and gooey tree gunk and junk. Due to my desire to keep the finest quality blades on the car, I'd only buy authentic Toyota blades for my 2003 Camry and then one day...

An associate at the local Toyota dealer talked me into buying the rubber inserts for the blades, rather than the whole blade assembly. For 20 minutes, I waited and watched as she fiddled around trying desperately to get the inserts into the arm assembly. Two days later (and 10 minutes of use later), while driving in a light rain storm, the whole thing came apart in pieces, scratching my windshield in the process. It was a Sunday afternoon (dealer was closed), so I drove directly to the auto parts store and told them I wanted the most expensive wiper-blade they sold. They took me to the Bosch Icon and said, "these are the best, but they're pricey."

I couldn't be more pleased with the quality and performance of this product. The two blades I bought for Cammie cost less than $50 which isn't THAT much contrasted against the frustration of not being able to see clearly through the windshield when it rains.

April 2008 UPDATE: I am on my second pair of Bosch Icons and I'm saddened to say that I am no longer "raving" about these things. While they're just swell for the first 60 days, they deteriorate quickly after that and become streaky and smeary. When I was buying wiper blades for my daughter's car, I asked the auto parts guy about the Bosch Icon. He replied, "I'm not that impressed with them either. They don't last long."

Good at first, then VERY bad.2
After reading many of the user reviews on this product, I thought I was making a great decision buying these. I ignored the occasional negative review and paid a good deal of money for what I hoped was a superior product.

I installed them (easy) and got to use them a week later at the first light rain. They were perfect! For about the first ten minutes... After that short of a time, I instantly noticed a hairline streak on the driver's side wiper. Then a few more hairline streaks just began showing up out of the blue. I even pulled over to visually inspect the blades to make sure no debris was on them. They were simply bad, bad wiper blades that had begun deteriorating rapidly after their first use.

I would not recommend anyone buy this particular brand of wiper. I havent tried competitor's brands of the same "no frame" wiper style, but certainly there is something really wrong with Bosch's rubber.

Today I still have them on because I simply cannot justify replacing them so soon after how much I paid for them. So I grumble and moan everytime it rains and squint my way through the dozens and dozens of hairline streaks that have shown up to date. But it will be a happy day when I finally can take them no more, throw them out, and return to the normal wiper blades we all know and love.

Absolutely wonderful!5
I own a 2006 Mazda 3 hatchback, and this blade has made a wonderful replacement for my drivers' side wiper. Initially I had procrastinated until wintertime, half expecting to find a decent winter blade, which I may have kept throughout the year. Well the first snow came, and I decided to pull the trigger. After unsuccessfully looking for the blade sizes everywhere (21" driver side 19" passenger side) including the owners manual, I simply measured them and looked for quality Bosch blades (the originals were Bosch blades, and they made it two years without any issues, just intermittent cleaning). While I had seen some Bosch winter blades, these caught my eye as a solid all season blade. While they specifically aren't winter blades, their compact size and lack of any kind of structure that could be prone to snow and ice make them ideal for snow belt residents.

Pros
Bosch quality--if you've never used Bosch blades, get some
ease of installation
clean streak free performance
no excess noise

Cons
both blades have lackluster performance on the outer most 1/2" at certain parts of my windshield due to curvature issues, which I could care less about, as its only at the far right of the passenger blade and the very top of the driver side blade.
