I've never thought much about windshield wiper blades. I buy new ones when they start to peel away from the wiper holder and usually have them installed when I get an oil change or at the auto parts store. I've never in my life even attempted to change the blades myself - until now.I began by looking up how to replace the windshield wiper blades for my car in the manufacturer's manual. I have a 2005 Chevrolet Impala and Chevy made it seem pretty easy in the manual. Unfortunately, when it came down to actually performing this task, the manual's instructions left a lot to be desired. It just wasn't clear to me which way to pull the blades to remove them. Chevy said to pull them towards the windshield, but that apparently means a different direction to them than it does to me. I finally figured it out after watching a video on YouTube after searching the internet for how to remove the blades.The instructions on the Bosch package were also a little ambiguous for me. It wasn't clear to me at first that there is a latch that has to pop up on the Bosch blade before you slide the shepherd's hook on the wiper through the blade. I will confess without shame that it took me nearly an hour to figure that out. In my defense, this was the first time and the old blades didn't have such a latch so it didn't even occur to me that the Bosch model would. Once I figured the latch out, the rest was easy.I actually really like the latch - the blades seem even more secure to me than the old ones I had. While I've never personally had a blade fly off the car while driving, I have heard of it happening and it never hurts to be a bit more secure. The last thing you'd want is to lose a wiper blade in a thunderstorm.When I got my oil changed in early December 2010, I had them change my wiper blades with some very inexpensive ones. They worked well enough. I replaced those cheap blades with these Bosch blades just two months later at the end of January 2011. Since the old blades were practically new, I was able to get a good feel of the difference between those and the Bosch 22A ICON Wiper Blade. I have to say, as someone who never paid any attention to wiper blades unless there was a problem, I do believe I can see the improvement. The old blades streaked just a bit - not enough to interfere with visibility, but it was there. The Bosch blades wipe the windshield very well, leaving a very clear view of the road without streaks.I ordered both the Bosch 22A ICON Wiper Blade, which I've reviewed here, and theBosch 22B ICON Wiper Blade, 22" (Pack of 1). I studied the product descriptions for both models carefully and also examined the two blades side by side when I received them and I honestly can't tell a difference in the 22A and 22B models. If there is one, it totally escapes me. They seem to be interchangeable and can be used on either the right or the left side of the car. Although some cars have use wipers of different lengths on each side, my Impala uses 22-inch blades on each side.The manufacturer claims that these blades will last approximately 40% longer than other blades, and while only time will prove whether this is true or not, having looked at the Bosch blades next to my old blades, I can believe it might be true.I would say that if you are looking for a better wiper blade, then the Bosch  22A ICONS Wiper Blade is a good choice.
