Bests & Worsts Reviews from Amazon

I'm not sure what the deal is with these Icon blades sold by Amazon, but these blades claim to have an Asymmetrical spoiler which means the little spoiler should be off center to one edge (which also resembles my factory blades). Twice now the Bosch Icon 22OE blade I have received from Amazon has the spoiler in the center of the blade. My truck also takes an 18OE blade which I also ordered from Amazon, and the spoiler on it was on the edge like my factory blades. This made my blades look mismatched. So I called up Bosch's tech support number and talked to a guy there and he confirmed that the spoiler on these blades should be along one edge and not through the center. He said maybe an evolution series blade was possibly packed in the wrong box, but to have it to happen to me 2 times I think it's a different issue. I ended up running to a local well known auto parts store and bought a 22OE blade and the Asymmetrical spoiler is along the edge like it should be. The one from the parts store also came packaged with several more adapters to make them work with many different models of vehicles and the Amazon blade came with none other than one that is pre-attached to the blade. I attached a pic of the amazon blade I received along with the parts store blade I purchased. The top blade is the amazon blade and the bottom is the parts store one (which should be what they all look like) I also attached pics of the packaging. I just don't understand why they are so different so I am giving these ones 1 star.
